Feminists and misogynists can bellyache all they like, but looks are always a factor, for basically everyone, otherwise there would be no such thing as 'heterosexual' or 'homosexual', and people would pair off seemingly randomly.
I doubt a 30 year old would tell you that you are too old and deluded - a 20 year old might, but by the time most people get to 30, they're mature enough to at least pretend to strangers that they're mature. Despite what some men on the internet say, most women are polite and flattered so long as a man 'hitting on her' is also respectful, and if she's not interested she'll let you down more gently than that - and if she does tell you you're a deluded old f**k, then she's not a nice person and you wouldn't want to date her anyway. Lucky escape.
Are you not attracted to any women older than 30? At all? Is it the family thing? I find that as I get older, my 'average age of interest' has remained quite consistent, and there are often women I see in their 40s, 50s (or I don't know their age) who I think are very sexy, but obviously, 'sexy' is very different from 'would want to be in a relationship with', because if, for example, you don't want to be father-figure to another man's children, that massively cuts down the field of ladies over 35 at a stroke. But, if you really want children, there's always adoption - there's no guarantee that any lady you meet of any age is going to want to have children anyway - and tbh, I'm amazed that any woman does, ever.
I view 'boring' peers as a double-edged sword, 3 of my siblings now have young chlidren, and my sister was telling me only yesterday that now when she looks at me she can't help but imagine that my life is one long round of bacchanalian pleasures, like eating adult food, not having to watch kid's movies at the cinema, deciding to go away for the weekend whenever, etc. So there's that.
