The OP gave no example, so I had to make a guess. In my experience, people that complain about "groups getting politicized" generally mean "a minority joined and was upset when we weren't inclusive."
Perhaps I should have simply left it at the question, but the internet is a frustrating place to have dialogues like that - clarifying every tiny point before running out of space for a counter argument.
He meant you were the example. I am not saying it was your intention, but the way you mentioned a particular issue and then added your opinion on the issue in your comment is one way people inject their beliefs into otherwise unrelated conversation. I know you needed an example to make your point, but the grandparent was trying to make a point of your comment.
