I actually agree with both of these points. In fact, these are just basic facts, what's there to discuss?
But if you say "here is fact X and I prove it by Y" where X is true and Y - exagerration or outright falsehood, why is it wrong to challenge Y? I actually find this a form of trolling, because if you continue slipping an untrue with well known facts often enough, then some people might start thinking - that other thing must be true as well.
> Neither of your three points explain why artists, especially writers, were deported.
That's a good point, I don't actually know any Lithuanian artists or writers that have been deported. Could you please name some of them? That would indeed invalidate my argument.
(Btw, this - learning something new - is exactly why I am trying to have a discussion at all, it's nice when people answer with facts, even if these facts change your position, instead of useless rhetorics.)
