Cheap attempt at a straw man, now care to address the question? Do you consider people who get RU passports, work for and receive salaries and pensions in RUB as collaborators? What about people that vote to secede from UA (like Crimea)? Care to put a number, roughly how many collaborators there are that you feel should be physically eliminated? And the part about the children of collaborators, what do you want to do with them?
You're reaching desperately, up to and including accusing someone else of "straw man" while yourself providing only dramatized straw man arguments.
Look up collaborator in a dictionary. It tends to be defined as a person who is part of the enemy government or military, i.e. basically a traitor. Probably a legitimate military target in any case, so killing them during war is fair game. But that's not about regular citizens who may or may not use rubles. Or children.
