You can't have a group that is inclusive of X and also of people who believe that X are subhuman, e.g. to be inclusive towards Jews you have to exclude antisemites. Or generally: to be inclusive of marginalized people you have to exclude the intolerant.
If you don't push away the intolerant then those who are discriminated against figure out they're not welcome in the group and so they leave. Those who remain are the intolerant and those indifferent to intolerance. That results in very bad communities.
