Is a grown man telling a minor to get lost in the forest as a reply to a post rude?

There was a misogynist that claimed to hate women. My post was about how I don't want to be another woman that wastes her time, years and it's all just sex. I want to get the right man and form a family early, not late in my 30's when it's too late. I understand there is the dating process but I can't take too many years into that; it goes against my own biology. I don't have all the time in the world to stay as a childless, girlfriend.

That pathetic dude was a grandpa himself and he was telling that I should get lost in the forest, no one will care about me. I just turned 17 not so long ago and therefore still a minor. Is that the way how you treat a minor?
