I've adopted a sort of military strategy to the whole thing. Since I became a brony in August, I've started using pony memes, quoting phrases and lines here and there in conversation, but without saying where they're from. I've even shared some funny pony pictures and videos with friends. So this is phase 1: wear down their resistance by saturating them with pony cultural references in ordinary conversation. Phase 2 will come soon: coming out and talking about the actual show behind all the references and stuff.
