hmm..ok.
try this:
not all people who are proud to be an American are white nationalists,many come from different cultures and races.
however,
all white nationalists claim to be proud americans,and that is what fuels their philosophy.
I say rhetoric,because that's what rhetoric does.
it doesn't make an argument,and rarely even makes a point.
but it does appeal to the "feels".
I kinda get where you are coming from in your meme,because I have had super lefties try to cuddle up to me because they mistook me for "one of them".
and to specifically address you and your meme:
it is not you,or any other proud americans.
it is the rhetoric of racist white nationalists that have created the connection of :proud american "oh,you must be a Nazi".
you can only battle that on a person to person basis.
use your words homie.
people will get it.
