No offense taken! Obviously, I’m not seriously suggesting anyone join ISIS or whoever these folks claim to be. Here’s an idea, maybe. Go visit a ѕуηαgσgυє with a Rosary in your pocket and pray it in secret. Or hide a green scapular or St. Benedict medal on the premises if the idea of engaging in stealth warfare appeals to you.
If you really know the Faith up, down, left, right, and inside out, plus are well conversant with Jєωιѕн beliefs, offer to debate a rabbi or other prominent Jєω. (But make absolutely certain you know your stuff plus the various strategies and tricks used by the enemy.) On a lesser level, openly fight ʝʊdɛօ-Masonic influence of pornography, the lies of the MSM, public schools and politicians brainwashing our children, laws that offend Our Lord, the public display of the demonic, and those Communists who’d steal from us our rights by God’s and natural law.
Unless I miss my guess, you’re a dedicated young manly Catholic, so wanting to engage in physical warfare for Christ is in your God-given nature. It sounds as if your parents brought you up right and didn’t allow you to be turned into a girly guy, so typical today. Maybe find some like-minded men and join or start an organization. And if you’re not married and don’t have a religious vocation, there are young single Catholic women out there looking for husbands!;) (I’m NOT referring to myself, lest someone on here get the wrong idea!)
