Jay Nordlinger has a long piece up on the increasing intrusion of political commentary into what ought to be pleasant, apolitical social or cultural occasions. (Via Instapundit.) It resonates a lot with my own personal experience, but I think he misses one point. Nordlinger suggests that the ranters are assuming that everyone in the group is a leftist like them, or are at worst indifferent to the feelings of any non-leftists. In my experience it’s worse than that; the ranters do so with the deliberate intent to make those who disagree uncomfortable.
Does this happen from the right as well? I can’t say, as I’ve never flown in circles where conservatives and libertarians are a sufficient majority for it to happen.
