That’s no excuse to say there’s something wrong with them (him? Dunno their pronouns). They do have a few issues, but it’s not right to point that out and make them feel insecure about it. If you were disgusted or offended at all by this post then you can at least not be rude about it. Technically for things like this you should just scroll away and ignore it if you don’t like it, but if you must comment, you can try to be nice about it.
Just a little word of advice for not making people feel bad about themselves.
