I don't mind he deleted all 4 posts but why he still have the lecture?
First of all, yes you do care. If you didn't, you wouldn't have gotten your fur standing on end and this thread wouldn't exist.
Second, Ratimov can say whatever he likes--just as you can say whatever you like (within the structure of the forum, obviously, which includes potentially having your posts deleted by someone who self-moderates their threads). It looks to me like Ratimov made a statement about his early days on the forum, which you followed up with some unwelcome comments about the Russia situation. Frankly a lot of members here are just sick and tired of that kind of discussion creeping into every crook and crevice on the forum.
You've got to grow a thicker skin around here, honey.
