If some people genuinely have problems and some genuinely don't, then only common conclusion is that the problems do exist (for some) and so solutions to them are required, so the experiences of the people who had problems can't be trivialized (because that experience is relevant for solving the problem even if they're in the minority) and the experiences of the people who didn't have a problem should be trivialized unless there's a good argument that those experiences almost universal and the problem actually is not real.
