Re the "fist jab" the host did not refer to the fist bump as a "terrorist fist jab" but, rather, included it in a list of things being said about it by others; the article I point to is clear on that as is any but the most biased viewing of the host's statement.  In context (E's reply to my "Why?"), he attributes the host's comment to "malicious intent".  It's not merely that the host uttered those words, it is the implication of intent about which E demonstrably  mistaken; yes, he is wrong about this as about everything else he has said regarding this particular article.
Yes. The "V", like many others, could be seen as a gang sign.  This particular one struck me, however.
