Do you find that they’re ok with over representation in area “x” because there is under representation in area “y”.

That would be the same for every group. By definition, if you are overrepresented in one area, you must be underrepresented in another area.

As for the first strategy, if someone calls you a racist, what are you saying is the appropriate response?

I never defend myself, I always attack them. If they call you racist, you say that they are the ones being racist and hateful towards whites. You say that they are the ones wanting to discriminate against white people, that you are anti racist and that you oppose their racism and evil ways. I do the opposite of what Ben Shapiro advices us to do, and I assume malice in everything leftists do. I want to paint them as the worst possible people because they are. They are liars, racists, evil, degenerate, pedophiles, hateful, violent, etc.
And it is easy to point it out because it is the truth.

They say love is hate. They say anti racism is racism because THEY hate white people. They make its okay to be white controversial because THEY hate whites. They are against white lives matter because THEY are racist towards white people. They promote immigration because THEY hate white people and want to undermine white people and because they love brown people. They hate christianity but defend islam because THEY hate white people and think of christianity = white and islam = brown. Antiwhiteness is an everyday thing now so you can literally just link to "todays anti whiteness" and shape the conversation against them around that. Leftists wont dunk on other lefties, so I simply say that this is how the left is and they will try to defend that its okay to be racist against whites.
If they do not defend the antiwhiteness, then its them admitting that antiwhiteness is bad and then you have to nail them down on it. An apology is a guilty verdict, as per SJW rules. So you single them out and get them to distance themselves from this antiwhiteness among the left. Just like how leftists have done for years to the right "No I am not a racist like those other right wingers". Make them defend themselves from your accusations.

I don't really go into a debate with a leftist to "debate" or "discuss", I go into a debate to point out how evil they are and I twist everything that is bad for whites as racism against whites.

Note I attack jews more than I would in other forums because it is allowed here.

I know this isn’t a Trump forum, but when Trump supporters “leaned in” to being called deplorables, that seemed to be pretty effective. Basically, instead of denying it and arguing semantics, hijack it, and put the burden on them to prove why their usage of that term makes it a pejorative.

Being racist can land me in jail for years so its not really a term that I can "own" or "hijack". It will also get you deplatformed in a lot of normie spaces with antiracism rules.
With my approach I can get leftists banned for racism on normie platforms.

And yes being anti immigration is being an anti racist and equality, because Africa doesn't have 13% white population so why should white countries have 13% african population? That's just antiwhite and racist and not fair.

Edit: They are the ones wanting to genocide whites so we are the ones defending and they are the ones attacking. That is just reality. Point it out. They are the ones being anti white and thats evil. Its not "hateful" or "bigoted" to defend yourself against leftists attacking you for being white.
