Funny how OCD seems to be the only mental illness people think it's OK to make fun of and minimise.
Is it buggery.
I have mild OCD and not so mild ADHD.
late MIL had severe OCD and severe bipolar I
Trust me, neither of us are/were heard to have a grumble along the lines of "how come you are all oh so sensitive about all the other syndromes, but take the piss so relentlessly out of the OCD".
If people feel the need to buck against the status quo I'd rather they spent their time/energy challenging the wide spread idea that syndromes are made up, an excuse to drug people into submission and controllable if the person who has it just "tried harder".
Next to that cakes don't even register on my radar.
Not that I give too much time to even the hardcore denialist stuff anymore. I'm too busy trying not to hyperfocus on time sucks and concentrate on the Shit I Have To Do.
In some respects giving a lot of energy to railing against even the decidedly more ignorant and offensive stuff is like shooting myself in the foot. Cos it takes far too much energy and attention away from things that will have a positive impact on my behavoirs and life. The latter offers me a positive impact in real time on my real life. Jumping up and down about slights (large and small) changes fuck all in my life, other than leaving me wiped out having spent all that energy on people who are welded into their position, or backing away slowly cos I am coming across as over-egged, obsessive and lacking in any capacity to perciveve nuance.
I'd rather focus almost entirely on fine tuning the real world strategies that will help me than give more than a cursory eye roll at well meaning but uninformed person, or even an outright areseholy one who is being offensive for the sake of the attention it earns them.
Being an activist is really appealing. But if I am honest it is appealing because it means I can sink into hyperfocus in an area that allows for mucho crisis and drama. Which is sooooo much more attractive than getting to grips with my dodgy ability to deal with the mundane. It's just... the only thing that will work towards a better future for me is sticking to the hard slog of increasing focus on the boring, non exciting shit that offers no opportunities for dramatic gestures and an increasing sense of martyrdom.
Which is a pity, cos I can do a fab line in poor man's Joan of ADHD Arc when given free rein to do so. 
Honestly love, if you want to make the world a better place, forget the cakes, look at your life and think where a bit more of your time and attention will make a measurable difference in your/your loved ones quality and enjoyment of life. It doesn't offer the same level of excitement and outrage. But short, mid and longer term will likely have far more of a positive impact on more lives.
