Mexican flag on private property

I just saw this video on what I'm guessing white woman who was filming a spanish woman who was in her own house minding her own business. Crazy chick who's got her camera in this other girls face says she was driving by and saw that the resident had a mexican flag in her yard, her own property. She vaguely insults this woman for barely speaking English but still talks to her repeating she's living in America and out of respect she should take the flag down. It upsets her. Blah blah blah.

I can't believe that someone would pull over, invade someones private property, film a stranger, insult and belittle them just to bitch and moan over a piece of fabric. Just some love of what may have been where she came from... what's wrong with showing some admiration for other countries? I have a German and Japanese flag in my house and I've never even been to those places! Who cares!

Do you think this woman should have taken down the flag out of respect for this wack jobs feelings?
