About Kelly, it is once again tricky because now when you don't support her message you'll be called a bully or not against internet hate. It is hard to disagree with her message, but it cannot mean no word or comment can be said about her.
She cannot be totally compared to other wags imo (or ex wags like Lu) because she was never entering F1 world as anonymous person, she had the backup wags usually do not have (I count Heidi out). She decided to live public life, post also her personal life and while I don't think it gives others free pass to hate or bully, it is related to people commenting your life and she has to accept people will be talking. You can't totally control them. I think she is just disliked and the comments that are more heated come in waves from time to time (now there is this wave caused by that rumour from the guy's ex wife), but I don't feel like she is the wag of main interest now. But suddenly will be seen as the biggest victim now (tbh I think some comments about Alex who shows little of her life compared to Kelly are much harsher). But I would not be surprised if we now see wags' union against hate comments lead by Kelly, the self proclaimed queen bee of wags.
Once again, not to blame anyone for who they parents are or what they did, but for the context let's remember Nelson is literally BANNED from the paddock for his comments and he is the one who has "Insulting language" section in his Wikipedia bio. And this section is not just about recent times (I just checked) - first mention is about 1988.
And for the record, I do not disagree with her message in general. I just feel like it is a bit manipulative because we really don't know exactly which rumour it refers to and combined with everything else, we are getting into narrative that wags or drivers (or famous people in general) can only be praised and worshipped and everything else is hate or bullying.
On totally different note, we need to agree, that if the situation was reverse, it was a dude with a younger girl, it would not be commented as much. Guys get free pass for everything. And still "she looks like his daughter not gf" lines are more a joke towars a guy, women dating younger guys get much more criticism. I am not sure though she was referring to these kinds of comments as they are old news.
