Because the 'pandemic of farm murders' does not exist. Every statistic on where murder happens in South Africa shows that they are exceedingly rare and no race in the country has LESS risk of murder than whites and the vast majority of the time when whites ARE murdered it's by other white people (the most common murder among whites is arguments with people they know which get out of hand, the most common murder of white women is by their [usually white] boyfriends/husbands).

These are the facts. The majority of farm murder victims aren't even white -  black farm WORKERS killed in these attacks actually OUTNUMBER  white farmers - and there is no evidence of political or other considerations - indeed no evidence that this is anything but robbery with the USUAL South African problem of excessive violence exacerbated only by the distance from emergency services and relative isolation.

Selective outrage IS racist. Farm murders aren't a thing, MURDER is the problem it's a tiny bit off.
