Sargon made the observation that if you associate any symbol (e.g. Pepe) with something hateful The Left will denounce that symbol. So, how about taking symbols The Left loves and associating them with hate so they are forced to denounce them? In order for this to work I suppose they have to be obscure enough symbols that most people will not have heard of them until CNN denounces them.
