No, it's fine. I understand that it can be difficult to hear that a discussion topic isn't relevant to the conversation at hand, and I know that you didn't intend it as anything other than an honest query.
As sugargroupie pointed out, though, the tactic of saying "Well, there are other types of oppression in the world, too, that are just as important, and people ignore them!" has often been used to derail discussions about race and racism, colour, and culture - and often tries to turn the conversation to a topic that allows the white people to be oppressed, too, thereby absolving them of any responsibility for the prejudice experienced by POC.
