Hannity wouldn't want BLM and their supporters to procreate, so he's not the one telling them to make babies.
Mr. X must have imagined one of two things:
1) The presence of Antifa and BLM supporters would get Trump supporters involved in a fight and thus distract from their attempt to invade the Capitol. Large groups of protesters against the MAGA crowd when it was still only a rally would also have meant the presence of more policemen in riot gear to keep the two groups apart.
In that case, Mr. X was trying to
help the insurrection attempt by making Antifa and BLM supporters as well as a large number of police that could have been redeployed to defend the Capitol building stay away.
or
2) Mr. X had inside knowledge that the Proud Boys, Oath Keepers and other militant fascists would be particularly well organized that day, and he didn't want BLM and Antifa supporters to get hurt in a confrontation with them.
In that case, he would have been trying to help BLM and Antifa.
Some kind of double agent? Somebody in the ranks of the militant fascists who is there as an informer of the FBI but sympathizes with Antifa and BLM? Like the one who
recently informed the police about the Patriot Front.
