When I was young whippersnapper, my mommy told me that it was infra dig to discuss politics, religion and sex in polite company.
However, by mutual agreement here when LSC first started after the LYSOL debacle, I was under the impression you could discuss all of them as long as the subject matter included all three.
e.g.
The politics of religious sex,
The religion of political sex.
The sex of religious politics.
