So, I made a post a couple of days ago talking about possibly using tactics from the Hong Kong protests in case all other paths failed. But upon thinking about it some more, I don’t think it would work except in urban areas, and most of the Trump-voting counties are either suburban or rural. Also, it is apparent that the police in DC and in most other urban areas is deeply corrupt and would do nothing to help.
What I now believe would be a much better idea is not for us to go to them - but for them to come to us. Some Democrats have already seriously proposed making lists of Trump supporters and rounding them up. We should encourage this, as it makes them the targets instead. Within each town or community, there should be teams of patriots divided into different tasks - for example a team monitoring communications and surveillance data to alert others in advance to get into position, a team well-trained with weapons, a team handling first aid, etc.
You are absolutely correct that there is no polite or civil way left to do this. What I am proposing is only the bare minimum of what patriots should be doing - at the VERY least, they should be prepared to attack when the leftists come by to round them up. But from what I’ve been seeing so far, many people (even on this site) are still unprepared to seriously consider the prospect of taking matters into their own hands. Many are still under the illusion that someone else will fix it all for them.
