You are illinformed on this point. The states laws against desecration were thrown out by the SCOTUS.
I will be honored to emolate a postage stamp flag that I have paid for, in front of Senator Feinstein. She can have me arrested, bear witness against me, and have me convicted. Maybe I'll get to know Wenyi Wang while I'm in the joint.
When you have to arrest someone for their classless acts, you should bone up on verbal retorts instead. See a big unilluminated flag at night or a prominent flag that is tattered? Be your own flag amendment and use your precious freedom of speech to convince the keeper's of those flags to straighten up and fly right.
