Not too sure. If this is just for an opinion, then I'd personally get new group members because your job is to help people instead of degrade them for things they don't have control over.
But if it's for an assignment, then I'd still say the same, but it's asking you what you'd do in the situation where you have a counseling program and your group members have been saying bad things about AIDS and the gay community but you're not sure about whether the group will work out or not.
