I'll go first. I had a take that if you see a bunch of advertisements saying to vote no on prop x, and nearly none saying yes on prop x, you should probably vote yes. Because if big money is behind an effort to sway towards no, there's probably corruption in the ranks.
As a German, i absolutely do not want Anglos to shut up about what my ancestors did to the Herero and Nama in Namibia, or how they brutally crushed the Maji Maji uprising, or how von Lettow-Vorbeck used indigenous forced conscripts to fight the Brits in WW1, or how Germany participated in the colonial subjugation of China. I also do not think anybody should shut up about the colonies of the Dutch, the Spanish, the Portuguese, the Italians, or France, or the Austro-Hungarian empire, and would not let anyone off the hook who is trying to excuse these. Yes, the British empire was, all in all, the worst due to sheer scope. That doesn't excuse anybody else, though.
