they’re not “anti antis” or “pro-shippers”, they’re enablers. enablers of grooming, abuse, sexualization of children, fetishization of rape, incest, abuse, paedophilia and dehumanizing, sexualizing and fetishizing the LGBT community, especially mlm.

Just so those "anti-anti" types who claim to be the real allies know, as a minor I have always felt so, so wary around you. You remind me so much of creepy people, especially men, who I have met IRL, and your attitude toward my objections about the work you produce (especially stuff involving adults and children and noncon) is flippant, disrespectful, and just plain shitty.
