Conservatives have won the popular vote for a presidential election exactly once since 2000, and it was Bush in 2004. They are, by definition, unpopular. Accordingly, you can expect that in open forums the conversation will skew against Republicans. You don’t get to enjoy minority rule and popular opinion at the same time, sorry. If you’re tired of being the minority in every space, perhaps you should consider trying to win people over. Here’s a good start: news.gallup.com/poll/1645/guns.aspx
The majority want stricter gun laws. If you don’t want to be derided, I suggest trying to meet people in the middle and discussing sensible gun control laws. Raising the legal ownership age to 21 seems like an extremely popular measure that the majority of Republicans even support.
Or you can go ahead and keep coping and whining about conservatism not being popular without an ounce of self awareness. Your choice. I suggest trying to be part of the solution instead of trying to stop the inevitable.
