Your link is broken.

I did read your original post though. Basically what I got from it was that you encountered a few people who were all upset by something you've said. Either you encountered some overly sensitive jerks, or the way you worded things to them did merit some offense.

I don't really want to get into which it was, and I didn't really get into the comments over on your first post because in my experience, that community can be somewhat toxic at times.

But to your question. Is there a double standard against men with a preference for masculine men? Not really. That you encountered a few people who took offense at your words (warranted or not), and googled specifically for articles criticizing that preference, is not proof, merely confirmation bias.

Just going forward, try and be kind. Don't put things like masc4masc in dating profiles, and don't say things like you don't like his femininity. Those kinds of things tend to set off red flags for some people.

When pressed on why you're not attracted to someone, rather than listing a bunch of traits that you think are negative, just say something like, "I don't know, there just isn't a spark there for me."

As I've gotten older, I've been surprised myself to see how my tastes in men has changed and grown. That's pretty common actually.

Good luck with this new guy that you posted about!
