The push for relativism as a cornerstone of society is one of the most absurd notions floating about in modern society. Relativism is not a foundation for a law based society.
We're in a position now where self-conscious secularist states are opposing religious fanatics not with ideological fire but with empathy for their point of view.
Figuratively speaking, a man who catches his neighbour sleeping with his wife apologises to the neighbour for her being attractive. What do you think of the aggrieved man?
You cannot unravel immigration and you cannot unravel radicalisation. You cannot fight terrorism with force. The only solution to this problem is assimilation and that assimilation cannot occur without a battle of ideas I fear the Western intelligentsia either don't agree with or lack the willingness to take up. Liberty, equality, freedom of speech, rule of law, and nationalism (Yes, that old chest nut) need defenders.
It also can't occur without strong support and voracious denouncements from mainstream Islam. Something that remains lacking outside of the hours after attacks like this, and which is consistently blunted by phantom fears of anti-Muslim backlash. Well guess what, if you're so god damn concerned about anti-Muslim backlash FOLLOWING radical Islamic attacks, DO MORE and do it loudly BEFORE these things happen.
Oddly, the self-critical Muslim voices tend to get censored, boycotted or lobbied against by the left.
And the modern conflation of anti-Zionism with antisemitism is disgusting and only indicative of the left's ignorance of a complex reality.
