With the GOP it's silly you have people saying cherish life one minute and then comparing hungry children to insects in another.
So, I hate to sound condescending, but do you understand what a political party is?
It's a group of people who gather together to form a voting bloc and select a group of candidates that are broadly compatible with the party platform. The more parties that exist in a nation, the more narrowly focused they are. In our system, we currently have two major parties, this means they are not focused at all.
In the GOP, you currently have Randian Objectivists and NeoScoialists coexisting in the same party. In the Democrat party, you have Marxists and NeoSocialists coexisting in the same party. And, in both, literally everyone in-between.
So, what is "odd" about seeing vast contradictions with a loose political coalition of very different people? Again, none of the organizations you are talking about are the Church, so none of them are indefectible.
This means they have vast defects.
The Republicans are very broadly right wing, the Democrats are very broadly left wing. The Republicans are very, very approximately Austrian in economics, the Democrats are very, very approximately Keynesian. They both try to do exactly the same thing: Appeal to a majority of Americans.
If you are surprised that political parties are inconsistent, then maybe read a little about political parties. Without both of those groups, those who want to protect life, and those who consider useless humans to be parasites, the GOP has no chance of creating a majority. Without both the hardline communists and socialist democrats, the Democratic party has no chance to create a majority coalition.
Now, imagine trying to appeal to those disparate groups of people, and you might begin to understand why politicians are liars.
None of this is "odd".
