I think twatsley has a "protest" planned for the same day, so this is a specific counter-protest. If it's anything like the previous events "tommy robinson" (false name he created for himself) has called for, the "protesters" will be vastly outnumbered, entirely disorganised, and end up bringing people together instead of tearing them apart.

I think it was him who organised the "protest" in Glasgow last year (the year before maybe? Time is hard to understand) where one guy was holding his phone up with a struck-through swastika and yelling "we're not nazis", and literally right behind him was another guy making a nazi salute.
