Is this rude ? Calling someone or something they do basic

This guy asked me out and I said yes and he asked me what I'm doing and I told him I was going hiking in vail . And he said I will withhold the "basic" comments for now.

I actually kind of offended by that comment like who cares if its basic and why do people say that anyway. I kind of dont want to go on a date with him if he's going to judge me on something I really enjoy doing .
