You're going to need to provide a source for the definitions you're using for "conservatism", "liberalism" and "universalism".
Without those, your comment is difficult to make any sense of, since the way you're using those words seems to differ from any sort of standardized definition.
I think we can both agree that for example liberalism and Islam are incompatible. So if you want to conserve liberalism you'll have to exclude Muslims. That's not universalist -> liberalism and universalism are incompatible.
