Hold up your nose and vote left wing in the West.
Conservatives do not change cultural things. All they do is be racist, make the rich richer, and slow down immigration. All these things are not to the benefit of diaspora Somalis.
Correct. Here is the thing they don't tell you: conservatives in the West are mainly liberals. Conservatism is a stance: you want to keep things in society the same or slow the rate of societal change. In the UK, the old conservatives ("High Tories") were not liberals.
Liberalism is centered about liberty being the ultimate good. Economic liberalism (free market fetishism) is a corollary of that as markets are the best way to mediate between free individuals. Conservatives in the UK are liberals and conservatives in the US have always been liberal.
In the West, left-wing parties (bar some communist ones) and right-wing parties (bar some fascist ones) are all liberal. This is the trap that they don't tell you about.
Yes some parties may be more racist than others and others give you more money. They ultimately subscribe to liberalism. That is why right-wing parties adopt most of the social stances of the left wing ones eventually.
