This is a leftwing tactic called bird dogging where a leftist pretends to be a far right caricature(Think of the actor outside of Reform party office in Clacton). Either to get the snapshot of implying a certain group welcomes extremists or to disrupt an event or both.
Google image search says the source of this picture is an anti Trump page of facebook.
This sounds just like when it was supposed to be Antifa doing all the crime on January 6. It could be a leftist Facebook page but that is obviously a Trump supporter. No leftist is that ignorant. Yep, let's rig an election so the Republicans will storm the capitol.
