Negative Comments on Fluther Question - why even read when clearly in subject?

i had these two quotes recently on one of my posts (and no it does not take a rocket scientist to figure out which one)

“What a horrible thing to speculate on.”
” This is a pretty messed up topic”

obviously MOST people get the meaning behind why I posted it. but i am concerned as I am a HUGE supporter of free speech. And as that freedom is seriously being eroded in America and elsewhere, I just wonder WHY do people read/comment on items that clearly DISCUSS the subject matter in the title? Seems kinda silly to me. It would be different if you did not know what the post was about. Myself I would never express displeasure over a post I CHOSE to read unless it is something illegal. I am just wondering how others feel or if they get the same experiences/comments from others.
