You got a negative response from me because you asked me a question, I gave a fair response and you got shitty. It's not that hard to understand, if you're rude to people then eventually they'll be rude back.

Re cultural or generational issue, oh come off it mate, if you ask for feedback and then attack people who give it to you, then what do you expect? For reference I'm also 30's, UK. Nope it's not that, you're just needlessly rude.
