Often tolerance of one thing leads to intolerance of another.
The most obvious example that comes to mind is tolerance of radical Muslims
pouring into Europe has led to an intolerant antisemitic Europe with no go zones
which are highly intolerant of infidels. Planet Fitness is an interest
example of tolerance and making people comfortable. It keeps out very fit
people so that unfit people won't feel uncomfortable. It lets transgenders
into female bathrooms which make's women uncomfortable.
