It's not like votes were important, really, it's not like your post will get deleted if it received a tons of dislikes or that your opinion will be the only way to think just because you received a "Winner" vote.
As soon as you share your opinion publicly, you're also taking the risk to get judged, the fact is, instead of having a group of people talking shit (or not) behind you in real life, here they got votes, and it's not supposed to matter which votes they give, as long as you can stand for your ideas.
You're not supposed to change the way you talk/think just to receive a "good point" to feed your ego. There are assholes everywhere, just find a way to deal with them, instead of thinking that they'll magically disappear one day.
