One thing about BuiQuang is, we don’t actually know a lot about them. Do they even have a successful relationship, or are they just talking out of their ass? Hard to say.
It’s hard to pigeonhole BuiQuang, because there’s not a lot of information; they haven’t posted a lot of stuff. But I can see that usually their advice hasn’t been all that helpful; e.g. telling a woman who got fucked over by her immigrant husband that she should just forget about him and move on with her life is pretty platitudinal.
