Do people like this actually exist?

So there was this one video on youtube about history of Lithuania. There was a specific guy who wrote many revanchistic and somewhat revisionist comments. Essentially claiming that Lithuania does not deserve to exist as an independent country, that the commonwealth is to be referred to as the 'Polish empire' and etc. etc.

I first felt reluctant bringing it up here but, it had brought some concerns to me that this collumn has presence in our neighboring ally country. I can't help but think that this perhaps is a troll of sorts to provoke conflict and distrust.. He had written over 100 comments under that video many being copy-pasted) although I have seen his comments under other unrelated videos. And yes, he does respond.

How many people are there in polish history community who have such expansionistic views? Or just in Poland overall? I have been to Poland twice, and didn't feel as though there is any such sentiment, though that may be because I was Warsaw.
