"I am subjected to body shaming & it’s something I have accepted."
Well apparently she hasn't accepted it, otherwise we wouldn't talk about it now. Kinda hypocritical of her to take this to social media again (as she does with a lot of things) with the sole purpose of, ironically, shaming the people who shamed her. That's like bullying a bully, some might say they deserve it but then again, you also don't fight fire with fire. She should just be the stronger person here and ignore it, in my opinion.
Also, Nia Jax's character and reason for success is her body, without it she wouldn't be the sore thumb sticking out of the women's division. So of course she's gonna hold on to this statement of "I love my body" for as long as possible, I would too. If Nia would lose weight, she'd lose her credibility and marketability, plain and simple. Being plus sized is kinda like her brand now, because being an amazing wrestler just isn't.
As far as whoever could have body shamed her goes. I'd say one of the 3 that just joined the locker room which are Mandy, Sonja or Paige. In my opinion those are the only logical options because the other women have been in the locker room with Nia for over a year now, so why would they randomly start talking shit now?
kinda find it funny how she posted a video of her running for 15 seconds as if that's some type of approval of her being fit. Once again, if you really don't care about what people think of your physique or body type, you wouldn't bother trying to convince them of the opposite. That's what you call insecurity. Either that or she just wants to make herself look like a hero for fat people. One way or another, she should just live her life the way she wants to and not make a big deal out of situations like these for attention or praise
