The more reasonable FTM blogs don't get into the "you're not really trans" thing, but some personal blogs post about how some trans guys (who see their gender as an identity rather than a medical condition, who don't hate their bodies, or who are more feminine or non-binary) aren't really trans and are "making real trans guys look bad". There are more "all these supposed trans guys posting their *vulgar terms for female anatomy* in the FTM tag, they must not be trans if they can show their bodies" posts in the FTM tag than there are the posts they're complaining about.
This is why I don't really blog a lot yet, though I'm trying to get more into it. I initially posted a photoset of me without and then with a binder, but then I took down the "before binder" photo because I didn't want to get "you're not really trans because you posted a picture of your natural chest" comments.
