I don't see any selective outrage. We'd be pissed about armed conservative assholes starting shit with liberal officers or politicians outside of their home too. We have, here on P-F, decried and lamented it when some open carry knuckleheads did exactly that outside of a liberal Texas politician's residence, if memory serves.
Secured slung long guns =/= Long gun with mag in at the low ready.
Public square for protest =/= residential streets.
Not sure how you can still be confused about this.
