It's like asking a neutral how come they criticise the rags for being shit at football but don't criticise City.
It's all about words, actions and behaviour for me, so while Trump, Vance and their supporters continue to be racist, sexist and otherwise offensive on a daily basis I'll be more critical of them than the other side.
When they stick to their message, when they focus on issues rather than personalities then I won't be as critical.
And you can rest assured that if and when Harris and Walz start with the racism, sexism then I'll be equally as critical of them. Although I believe there is a "I expected to be cunts so I dont need to criticise" exemption available.
PS. Trump is the rags, and Harris is City in case I didn't make it clear.
