@benroyce but if you reject someone you aren't wholely tolerant anymore. You create a partition of that which you are tolerant of. If you reject only the intolerant, you create a tolerant subset by ousting, in the same way an intolerant group ousts the ones they do not tolerate.
Morally, you make yourself superior in claiming intolerance is an inferior position to take. Again partitioning into subsets.
I think I more or less embedded 'practical' in the two cases stated.
