I'm autistic. The r-slur is not ours to reclaim. We were never the intended target of the slur. Even if we sometimes catch strays. If catching strays was enough then everyone who got called The n-slur, r-slur, d-slur, t-slur, f-slur, etc. by a bully as a kid could claim they're "reclaiming" them. I don't get (or want) to say the n-word as a pasty-ass white person just because some racist little shit called me it on the school playground. A cis woman mistakenly called the t-slur, no matter how often, doesn't get to say the t-slur.

If you want to get pedantic and technical, the r-slur is derived from the old clinical term for "intellectual disability". Autism is (officially, though I take issue with it classed as such) a "neurodevelopmental disorder", not an intellectual disability. If you have both you could possibly make an argument, not my place to adjudicate at that point, but then whatever legitimacy your argument had would not be because of your autism because your autism isn't relevant to the use of the r-slur.

It also frequently seems the type of person who does this uses the r-slur as a pejorative. That's not reclaiming a slur. That's just using the slur as a slur at the expense of those it targets. You reclaim a slur by using it for yourself or others (if you know they are ok with it) as a term of *pride*, endearment, humour (fine line), resistance and resilience.

When I say I'm a dyke, I say it as a point of pride. I say it because it's not a negative thing to be called. When I say I'm queer, I mean "I'm queer as in 'fuck you'".

I can appreciate some autistic people who are struggling in our deeply ableist world wanting to be able to use the r-slur because they may have been called it. To try to gain some power back, but you're doing it at the expense of another marginalized group. That's not ok.
