This echoes exactly what the older liberals think because most of them only watch mainstream media they echo the media's message. My father is one of these people so I understand this angle perfectly. These people think BLM for example is a predominately good movement with a few bad actors and that Trump's hate speech is what's causing these few bad actors to act out. In these people's minds if it weren't for Trump there wouldn't be any problems. That's probably how these liberals feels that the leftists are only lashing out because of Trump so if it weren't for Trump they wouldn't be doing what they are doing.

Unfortunately, these liberals haven't figure out that it's the leftists pushing that is causing everything and Trump is merely defending against the push from the leftists which has been the case since the start.
