Even that is overstating things some things; it doesn't cost us anything in pleasure. The pleasure of habituation and familiarity is easily replaced with new habits and familiar things that bring exactly the same joy. More importantly to me, it unlocks so much meaning that was kept from us by carnist defense mechanisms and the need to protect ourselves from our own cruelty and violence. I don't think there is anything more important to experience in life than meaning.
But "pleasure" also understates things. I place others' right to existence and self-ownership not only above my pleasure, but also above my convenience, my comfort, and my financial interests. In fact, above everything short of the survival and ability to thrive of a human or any others that I love.
Re: sitting among others; I have noticed that I experience a lot more love and compassion for creepy crawlies than I did when I converted nine years ago. Still some (greatly lessened) healthy fear but never revulsion or disgust. It does feel good to expand my circle of concern and compassion and to feel part of something that isn't so unrelentingly human.
