The left can't stand it.
We've appropriated the a-OK sign, we've appropriated Pepe, we've appropriated milk. All we need to do to destroy our political opponents is appropriate things to make them mad. People on the fence will see their insanity and oppose them too.
I've seen threads about appropriating the rainbow flag as a symbol for racial segregation. This is a great idea! But we need to think even bigger.
When it comes to words we should make socialism our thing. We should make caring about National Heritage our thing (both concerning historical monuments and our nation's nature). We should make caring about your health and the health of the nation our thing. Put emphasis on those parts of National Socialism.
We should appropriate the anarcho-communist flag. It already has the right colours. We should appropriate the hammer and the sickle (although mid-way: sickle-and-gun, or hammer-and-gun I like more, symbolizing the importance of work and national defense). We should appropriate every symbol they hold dear, while holding on to our political ideas.
When it comes to number we should make them ours. We already have 14, 88 and 18. If we make sure everyone knows those numbers are ours, at some point some SJW will freak out about how mathematics is for Nazis. It would be even better if we could make just 8 ours. It already has the symbolism of the octagon representing the state between heaven (circle) and earth (square), which I think is a good symbolism for the Nationalist Socialist state: the closest man can get to heaven on earth. Plus: we're on Holla Forums here ;-)
They will start seeing Nazis everywhere, even more than they already do.
