Is mansplaining real in the workplace?

I work in a male-dominated sports environment. I’m also venting now. In my job, my superiors have only good things to say about me. But my male colleagues completely put me down and belittle what I do, all the time. Today 2 men at my workplace mansplained how I should do my job – and they are not even in the same field of work as me! But it’s getting so much that sometimes I think I’m actually the idiot, and they’re right. Surely being a woman can’t make me that much of a target for this stuff…. maybe I’m actually an idiot. But my various bosses tell me the opposite.

I see guys with the same job as me constantly get away with all sorts of bad work practices and I often think “gee, if I did that, I’d for sure get criticised” – can discrimination really be that bad? What should I think. I’m angry.
