Yes i know this is old but id like to kindly disagree. Yes people have been attacked and belittled for having odd yet truly harmful intrests. There have been cases where people are hurt for being into things as none threading as BDSM witch is completely safe as long as its practiced properly, or being a man and femdom attractive. Or a shining example is the fact a cartoonish fetish like vore is often labeled up to the same as actually harmful things like r*** and n****philia in pages "most hatted fetish" now im going to be honest i dont see any problems with someone not personally acknowledging them. But in the end those people are doing it more for themselves. Not for you. They use flags or use pride to remind themselves that they arnt the villains people make them out to be. And yes, especially media makes them out to be gross disgusting creatures and often try to draw unsubstantiated parallels between them and paraphilia. Witch is factually harmful to those innocent people. As it happenes to gay individuals.
Id just say live and let live. You dont have to be interested but you also shouldn't s*it on someone else parade.
