As a true liberal, I believe the writer has the right to his opinions and to express them.

However, it is disappointing that the writer has no clear idea what liberalism is.

It reminds me of political slogans along the lines of "Freedom, integrity, prosperity!"   So, let's find the party campaigning for "Opression, dishonesty and poverty!"   Now look at this guy campaigning against liberalism... so does that mean he woul be claiming to campaign for illiberalism? ;0)

Liberalism is about genuinely respecting the other person's right to his opinion, and recognising that, whether you agree with them or not, they may have a valid point to make, or at least a resaon for holding that opinion. That's not the same as saying that all opinions are equally valid, or that there is never a time to say "No".
