I never heard that Jenner got breast implants (or any surgery at all). I assume that is photo shopped.
I just thought it was a funny (or sad) meme.
The last time I saw him on TV was at Ma's, it was a blurb about dreamers path to citizenship. I didn't notice whether there has been any unnatural enhancement.
The only attention I pay to Jenner is disqualifying anyone in politics or the media that refers to him as a her... Hannity and the rest of FOX, the Republican Party and I think even Trump, I'm looking at you.
Biological sex is not a social construct, so referring to him as a her is propagating a lie.
