This is a great thread even if nostalgia ain't what it used to be.
My own generalised view about Glasgow pubs, which I could back up with a load of boring near facts & anecdotes, is that, with the exception of a few well known glaring examples, they're not exceptionally one way or other.
If you really want to visit an OTT Rangers/proddy tavern or a Celtic/cafflick howff you have to travel to the likes of deepest Lanarkshire or middlest Fife to discover real Bigotville.
