So, you want the government (Donald Trump's government, today) deciding whether you have a "genuine reason" for owning a gun.  If he decides you shouldn't own a gun, his henchmen will come and confiscate it from you - using force, if necessary.  As long as we have that on the table, at least I know where you (and presumably, most Leftists) stand.

And, why should I do 3 seconds of research when I know you'll do it for me? :)
