If there was a plan to attack the media at the rally, they probably would have followed through with it, Q shirts or not. After all the buildup by them painting Q supporters as violent and Trump's "media is the enemy of the people" preamble, ANY attack on the media would have served their purposes.
Trump supporters = Good.
Q supporters = Better.
Yes, it's very interesting to note that they were making people turn their Q shirts inside out yet there's a picture of Valkyrie woman inside the rally in her Q shirt.
The plot thickens.
