So this place is like reddit where feelings are more important than facts, and it is forbidden to say anything negative about someone who vows for the genocide of whites in the western world?
I believe it's more of a matter of etiquette. Rather than use an emotionally charged statement like "he's a dirty wog", it would be better received to type out something like, "Khan's mayoral policies are the result of influence from a culture that many would say are backwards in their beliefs. As such, he has made London unsafe for natives and immigrants alike, in my opinion. I believe that should his trend of governance continues, London will have violence and crime comparable to Middle Eastern cities. I would also like to note that sanitation has suffered serious setbacks in recent years and I believe it is no coincidence."
And if you wanted to go the extra mile, you could post a link to an article where garbage was simply being tossed into the streets in some specific areas. People tend not to listen to you if you have a short statement that sounds like something a 15 year old edgelord would say. I'm not calling you one, mind you, merely mentioning that Voat-talk doesn't carry much credibility here it would seem.
Mayor Sadiq Khan, as a dirty wog, thinks London is one of the safest cities he has ever been in.
