Judging from the examples you gave, I disagree with this conclusion. It looks more like they're trying to make liberals and conservatives look bad to each other, by playing up stereotypes. The primary aim seems to be to divide.
They also talk to each other, creating super confusion about who is real and who is not. Maybe those responses are written by bots too, to make us think some are real?
The sheer quantity of lies, especially lies that have nothing to do with the topic at all, leads me to believe the aim is a lot more than "to divide". The aim is also to disinform and to waste time of good people, who could be doing more important things but now feel they have to stop the spread of lies.
I apologize for my sample being incomplete and the summaries not sufficient. You really have to be there in the trenches seeing it happen. Check the next big news megathreads and you'll see it.
100s of comments per minute, many of them fraudulent and full of lies. You can go there and pick apart the details yourself to come to your own conclusions about it.
But you have to go there live - they delete their comments so rapidly that future study of the events is very difficult.
