In all honesty, does anyone actually believe that admittedly stupid comments like that were really meant literally? As in actual dogs hunting down the tens of millions who didn't vote for Trump?
I mean, does anyone actually believe that?
Oddly enough, if someone angry makes a threat to my life, I take it very seriously.
Some keyboard commando stupidly making blanket threats in a public forum just might give some more motivated angry idiot real world ideas.
It only takes one.
For this reason, people are expected to not make threats against the physical being of others on the web in general. Aside from being stupid enough to provide evidence if something should happen to the person they threatened, it is considered by most to be bad form.
I sleep light, anyway, and between that and the dog, won't lose sleep over it. But am always ready to deal with anyone who tries to act on a threat.
