I would attend a pro 2nd Amendment rally in a heartbeat, if one were held in Dallas when it's not 100+ degrees outside.
(And no, I'm no snowflake. I've worked outdoors in my own business for over twenty years, and for twenty years before that.)
There are several reason I won’t go to such an event, even the the 2ND Amendment mean everything.
IRL I am a political incognito. I am not going to advertise to this country’s lunatics what my political positions are.
Secondly, if I did attend such a rally, and some black clad ass started to threaten or harass me, I would respond. That’s just the way I am, so I avoid that situation.
