I think that in practice people worry that the tactics used indicate that actual inclusivity isn't the true goal, and the true goal is to create a new hierarchy with 'their sort of people' at the top and therefore 'our sort of people' being thrown out - i.e. inclusivity of everybody who agrees with us and let's just round everybody else off to bigots. My personal opinion is roughly that, yes, that's potentially a failure mode, and one we should watch for, but that people are probably far more worried than they need to be about it - and also that the tendency to dismiss such worries with "but how can you be against inclusivity" is rather missing the point and just makes things worse.
