In most cases, it is more useful to ignore any criticism, and even more so not to get involved in a dispute, you will only waste time trying to prove something to another anonymous person on the Internet, so this is a waste of time, anyway, everyone will remain with their own opinion. It is important to separate such concepts as dispute and discussion. In discussions, you can note for yourself some new facets of the issue under discussion, because the people leading the discussions try to supplement the subject of this very discussion with various arguments, while in a dispute, each side simply tries to defend its point of view, ignoring or trying to devalue the opponent's arguments.
