How can she blame sexism? Sexism didn't tell her to threaten a sitting president by holding up a severed head made to look like him did it? Of course it didn't. Don't be ridiculous.
This just pisses me off. The fact that she's trying to lay the blame on the Trump family when she is clearly at fault disgusts me.
If this had been a white guy it would have still been the exact same reaction. They would be investigated by the secret service and they would also face possible criminal charges, as they should. Regardless of sex, this type of behavior is considered threatening a sitting POTUS and should be treated as such.
