The rightists do not show tolerance to those right of them. They loudly denounce those to the right of them.
Why are you even asking why this happens? As you know, this "right" has nothing to do with supernatural Catholicism but is a human construct. Therefore, it is susceptible to human respect as well as to the fame-seeking of those politicians who embrace it, and who can alter it or water it down as necessary in order to get the necessary votes... Even by using their terms "right" and "left," you are playing their game.
Democracy, like Marxism, preys on the naivete of the masses, just like the snake telling Eve she can be like God, making them think they can have power, in this case, true representation. Instead, what ends up being represented are the most powerful and rich lobbyists. In an anti-Catholic world, the Catholic Church has no clout whatsoever, it is the Jєωιѕн, gαy and "humanitarian" lobbies that have the juice. Therefore, the real enemy of all these people, left and right combined, is Catholicism. Even their purported hatred of the "far right," represented by perhaps Marine Le Pen in politics, or Bishop Williamson in religious matters, is part of the Hegelian trap. These figures give the "moderates" a nice target to shoot at, as well as giving a voice to the fringe groups, but even they aren't really holding the Catholic truth, not all the way. So they are also part of a false right, though called "extreme right."
As I've written elsewhere, if even the "extreme right wing" does not hold all the Catholic truth, this is a perfect way to marginalize us. Because that makes us even more extreme than the extreme right wing, and thus so loony that we are not worthy of mention at all. That is why SSPX, a false Hegelian opposition of the false right, are treated to "talks" in Rome, while the sedes are marginalized and treated as extremist backwater loonies, so far out to lunch that it would be beneath this heretic usurper in Rome to even mention us... The SSPX is flattered, however, by the semblance of power they get in being taken seriously by these FRAUDS who are NOTHING, playing the game, having their "excommunications" lifted, arguing back and forth pointlessly, and so on. For those who see it clearly, that it is all a game, it is SICKENING. The devil's game is to totally marginalize those who could do true damage to him, while using flattery and human respect to cajole others into going halfway.
Sorry if this sounds arrogant, but put me on TV for a while instead of Michael Voris. See what happens. Of course, that won't happen. Because they will let someone who tells 80% of the truth through, but not someone who has the whole truth. Such a person is way too dangerous. But today, we aren't martyred, we are just kept on the fringes and treated as kind of harmless loonbags. And what is worse -- we are becoming comfortable with this situation. It is ingenious, what the devil is doing.
There should be no "right" or "left" just Catholic or non-Catholic. I can't remember hearing about "right-wingers" in medieval Europe. Right away, that opens the door to deceit. Once you replace the truth with a political approximation of truth, human respect will do the rest of the work of destruction.
Everything becomes relative and based on convenience. You can only be as "right" as the culture allows you to be at a given time. See: Marine Le Pen defending abortion as a secular value of the Republic, yet tagged as "extreme right wing."
Of course, this was all part of the Hegelian design of the Masons, to control both sides. The devil knows very well that people don't like to feel they are dupes, so he has to give them the illusion of choice.
Another ingenious scam is that the devil, knowing that desperate Catholics will adhere to whatever calls itself "right," can associate the poltical right-wing with non-Catholic ideas, such as the war in Iraq or economic liberalism. People forget that Catholics at one time were almost all Democrats precisely because the Church taught that the welfare state, unions, and so on, were better than nothing ( though ideally it is Christian charity that should put people on their feet, rather than government intervention ). American Catholics of today now think this is "socialism," though in reality it is the teaching of Leo XIII and Pius XI! They have become defenders of rapacious psychotic corporations, or they defend the Iraq war, or even the state of Israel. Just because the right claims to be against abortion -- without ever doing anything about it -- they think they have to go along with the whole program. They don't see the snare. Their minds slowly get infected and you can see a slippage in the love of truth.
