This is correct to a degree but it is debunked by the President's plain language in his speech prior to the violence at the Capitol where he asked the crowd to "peacefully and patriotically" protest at the Capitol.
It becomes difficult to make the accusation that the violence is incited when it is very explicitly said that the protest should be peaceful.
During the nomination of Justice Kavanaugh, members of Congress were confronted in elevators and hallways of the Capitol building by protesters. These protests were also based on unproven accusations and the people were weaponized to seize power as a ploy because they did not have the requisite votes as per the constitutional process. Intimidation and invasion of the building was seen very differently when it came to a lifelong appointment of a Supreme Court justice.
I would argue that the politicians from both parties share blame in allowing the discourse to escalate like this. To condemn only one party for it is not helpful at all.
