This is just as valid an approach as any of the late-night folk do on this issue & I welcome a "fellow-traveler" in this fight. It was well done, whether you are a fan of show tunes or not. Those that complained about that I believe are missing the point & don't realize that any friend on this issue is a valued ally in this fight!
Show tunes? I'm not gonna click play to give him views/income. (I don't think Facebook pays for video content views yet like YouTube does - but still.)
There's nothing wrong with show tunes per se, but it looks like he's going to trivialise the debate about the NRA, guns or that NRA spokesperson.
