Salaamu alaiykum
I think the OP could have been worded much better. Less of the emotion and tangential bad words and more intellectual criticism. There are ettiquetes for warning against other people if I'm not mistaken, even if that person may be doing a lot of harm. In fact, tending to emotions will make the very people you aim to convince tend to their emotion and actually become more motivated to go against what you say. We have to be rationalists. This is a reminder to everyone including myself, and I'm not just pointing to the brother and standing him out. I've seen many such behaviour from other individuals too.
