Your own views, as disgustingly selfish as they can be, are not being called extremist. Stop getting your underwear in a twist over people legitimately saying someone who holds the same type of views as you is extremist in their views.
Wanting to end all immigration? Selfish, backwards thinking, ironic given your stance on free markets. Wanting to kill people that you feel have advanced the cause of immigration too far? Extremist.
Your tendency towards the traditional family unit, and fear of homosexuality? Old fashioned, bigoted, sexist. Wanting to kill people that work towards gender and sexual equality? Extremist.
I hope you can see the difference, and in the future maybe see the same differences between your Muslim kin too, you're really not all that different.
