If government had to confiscate properties of all BLM rioters, would you support your government or fight for rights of protesters ?

Before that happens, the constitution will need to be re-written.
Here's a better thought, Pass a law forbidding anyone who is not a US citizen from owning property in the US. Likewise, all business not based in the US may not own property either. All properties should be seized and auctioned off and the proceed go to reduce the US deficit.
