Because then you end up with a ministry of truth that has to determine what speech is "clearly false". E.g one could make the argument that "nuclear power is unsafe" is "clearly false" given the facts based on deaths per watt-hour generated. You've already highlighted examples where partisanship breaks this down, in the case of BLM.

What happens under this setup when, say, a Republican president wins under an extremely narrow margin and subsequently suppresses discussion of electoral fraud? If in 2000 the government cracked down on people claiming Florida was fraudulently tipped towards Bush, would you support such a system?

Also, harassment is already prohibited. People mistake what harassment really is (people receiving speech they didn't consent to receive), with other people saying things they don't like between each other. For instance a university administrator claimed students bad-mouthing her on YikYak was harassment. It's not, since this professor could simply not use YikYak. Harassment protects against things people say to you, but not what people say about you between each other.
