Be more polite? Please be more insensitive I would suggest.

We're in the internet where people can just speak what they want to speak. Where people can say what they want to say. Do you expect that people will be polite on you especially here? Probably some might be, but most will not. I'm in a country where people online are mostly trolling, speaking offensive words in social media, and it's ok because it's called "Freedom of Speech".

If you are that sensitive here in the forum then you have 2 options. Either you adjust if you want to continue, or you find another forum where there is no freedom for users to speak what they want to speak (but I doubt if there is a forum like that). Please don't be sensitive too much OP.
