Well, obviously the use of violent gun-based imagery to talk about political action is the big number one there. But there's something else: the word "instead". It's unnecessary and clunky; it breaks up the flow. Why didn't she just write "Don't retreat, reload"? See, much snappier.*
So not only does Sarah Palin fail at holding any sort of office, and making speeches, and answering interview questions... she can't even write slogans! She's WORSE THAN USELESS.
*And that's even ignoring the poor punctuation! It should really be, "Don't retreat; instead, RELOAD!"**
**For that matter, the whole tweet reads:
'Commonsense Conservatives & lovers of America: "Don't Retreat, Instead - RELOAD!" Pls see my Facebook page.'
Sarah, you have no standing to talk about common sense. And why is "please" abbreviated? Spelling it out wouldn't come close to going over the 140-character limit.
