Why? because their only goal is victory and totalism

Only non-Leftists have to be civil: 


And a look at Self magazine's article, "Would you buy a gun?"

The article gives examples of women who accidentally (?) shoot husbands or have a mishap with a gun. The article points out that few women protect themselves with a gun. Really?

Why the soft propaganda?

I snarkily commented, "Because their hard-propaganda writer was on vacation." 

But the real reason is very simple: The Left believes in total victory by any means whatsoever. There is no tactic off limits, none that transgress the line of decency or civility because winning is the highest virtue of all. Their objective is nothing short of totalism, and whatever they must do to attain it is not merely acceptable, it is desirable.
