I find it offensive and extremely racist. It has no place in a business such as Amazon. How do I force these companies to stop advertising BLM. If they are not willing to promote Alt-Right why are they allowed to promote BLM?
Anyone can sue anyone for any amount of money. But you are going to lose if you file such a suit, I believe.
If you are serious and willing to spend thousands of dollars paying an attorney to file a frivolous suit perhaps you’ll find a taker. I think your lawsuit would be dismissed for lack if standing or failure to state a claim, however.
