I remember being an avid Alex Jones listener back in 2010 and under one of his rants about The Globalists there was a YT comment something like "hey everyone just check the ethnicity of every person mentions as a globalist in this video and on his show, you might be in for a surprise." And I did that and like 80 percent were jews and that was the start of me noticing as well.

All it takes for some is for someone else to point it out
