Thin Privilege: An Update

After another lively debate on Facebook regarding this topic I spent most of the other night thinking about it and my reaction to it. 
Is this where I suddenly repent and accept my thin privilege? No, it isn't. I still don't like the term, the concept and everything it entails and here is why.
When I read the original article and the comments associated with it it made me angry because deep down I didn't think I was getting any kind of privilege for being thin. Yes as a man, and although I really didn't want to bring race into it, a white man, I fully acknowledge the society we live in has been constructed in my favour. I accept that, and if it will change anything, which I doubt it will, I acknowledge that privilege. 

The comments I received mostly seemed to indicate that I was denying that "weight bias" "body diversity" "Sizeism" and so on existed, which was not the case. What I didn't like was first the assumption that people are "naturally thin", and that my life is easy because I am thin, You have no idea about my life just as I don't about yours, any assumption based on appearance is wrong. 
This point didn't seem to be accepted and I continued to receive anecdotes about people's lives and how they struggle with discrimination, which, at the risk of sounding like a stuck record I didn't deny existed.

After being directed towards research around weight bias and wages, a couple of points jumped out at me and made me rethink why I am reacting this way. 
In an article in the Journal of Applied Psychology (1) it was demonstrated that thinner women get paid more, not surprising, but the opposite was true for men. In fact, larger men get paid more up until the point of obesity. And a quote lifted from an article on Forbes (2) based on the study said. "Skinny men, indeed, are often regarded as nervous, sneaky, afraid, sad, weak, and sick, where men of well-proportioned build are associated with traits such as having lots of friends, being happy, polite, helpful, brave, smart, and neat." 

So is this really "Fat Vs Thin"? Or is it just another example of different rules for men and women?

I started thinking through my experiences in work and the times I've had to say "yes I do eat" or "no I am not addicted to heroin", did me being a thin man (as opposed to just thin) have something to do with this? 
Or the times I felt I wasn't taken seriously in staff meetings. I had always assumed it was because I was one of the youngest in the room (sadly no longer the case) but maybe it was because I was thin? 
While I can still find clothes that fit me in most shops I have noticed that I have had to drop down a size from M to S with no major change in body weight. It appears that provisions are being made to spare men's feelings by simply shifting everything up one size which is not happening for women. So is this really "thin privilege" or just plain old sexism? 
Is it possible that as a man "thin privilege" doesn't extend to me? Or at least not as much as it does for women? 

Rethinking where I stand on this topic I still reject the term thin privilege because I think it diverts away from the real issue which is what society expects of women. It looks like as a man I can put on a few kilos and not suffer any negative consequences, up to a point, whereas women cannot. And to me that is sexism not thin privilege.
