"Individual liberty as a protection is not part of the axiom of modern day "liberal" concepts."
I don't know what a 'liberal' is for certain, but, as with most political groups, most of that group's members are probably not certain, either.
It is possible, however, for one to think that one's own safety and liberty is made more sure when as many others as possible are happy.
Theoretically, protection of the individual is at least in part bound up with protection of all.
Liberty.
Equality.
Brother(and Sister)hood.
Love others as yourself.
Hence why forced tolerance is not a liberal concept. Authoritarian it is, liberal it is not. If it were true that the todays liberals cared about the happiness of others, they wouldn't be so quick to use government's monopoly on the use of force to exact their version of "social justice".
The last 100 years is ripe with the hypocracy of this concept. Special interest groups is what todays "liberal" focuses on, not the individuals liberty. Or we wouldn't have force racial integration, forced participation in government ponzi schemes, etc.
Liberalism died years ago and was replaced by special interest group "liberalism". Which is both a modern day republican and democrat position. The only difference is in which way these two groups wish to apply force onto everyone via the iron fist and for what cause/idea.
