Why are people so against ?

when ever someone asks a question on the internet they get like 1000 answer saying they are dirty hiv std's ...most people already know this stuff and dont need to be reminded. theres protection against most of them anyway if a girl asks one about ual exploration she is instantly a slut! what the hell why is it such a bad thing if you hate so much why even comment on the questions anyway just avoid them and crawl back into your caves (by yourself since you hate so much)
