If someone said that to me I'd have thought they were rude. Social media on any level tends to make people very brave. Brave enough to say things online they'd never have the guts to say to your face. That's why I quit Facebook years ago. I'd see them and I'd say I saw what you posted and they'd run off flustered. If that's how they are in real life then that's fine, that's how they are. But there are more polite ways to talk to someone (especially someone you don't know) than put on your big girl pants or don't own chickens. Just my opinion.
