I have lots of interests other than guns. With guns, there's not to many social outlets to talk about guns. Some circles, gun discussions are a no-go. Sometimes just slightly taboo. Extreme cases you can find yourself unemployed if you mention firearms. In other words, I get my gun chatting done on TFL, for lack real life venues.
I'd have to say a minimum of 3 hours a day... for the past 5 years.
