FWIW that video is heavily edited, and the campaign released a statement that a group, including those women, were refused entry because they were disruptive at previous events.
Now, I think Kamala and Biden deserve the protests, and they should be doing something, anything, to end the genocide in Gaza.
But it's a political rally. If you protest at one of these, they're not going to let you into the next one. It has nothing to do with your religious headwear or islamophobia or sexism or terrorism. Claiming discrimination when there isn't any is disingenuous and counterproductive. It lends credence to the people who dismiss legitimate complaints of discrimination.
