Why me, how in the hell did I get drug into this? Since you asked...
I generally don't like people having to answer for tweets that are a decade old. That being said I don't feel the least bad because of how she misrepresented why her tweets were problematic.
Yes, she had to deal with sexist trolls, and that's very unfortunate. That isn't license to call people faggots. She wasn't some high school kid, she wasn't even in college, she was a full blown adult calling people faggots in a public forum. Those tweets were deleted after she got her ESPN job and she has a lot of problematic content on her account, and she really didn't do much to clean up her behavior on her feed, nor did she apologize for or attempt to make good for how she acted until it cost get a job.
ESPN's problem is that they didn't properly vet her before hiring her, it's the same damn thing that happened with the pardon my take guys and their content is much more Disney friendly than Kelly's. She had a good job with CBS that she presumably had to quit, I don't know why this took Disney so long.
Ultimately she'll be fine, she'll continue to make money the same way she has the last 15 or so years. Hopefully she'll be better for this, and she'll get another big break. Frankly I have no idea how she wasn't already with Barstool and Penn National Gaming.
