Ideology is a poor substitute for kindness and decency...

"When democracy is failing you have to resort to any means necessary as long as it is peaceful and does not harm other human beings"

If throwing green custard on someone's face cannot be defined as harm to other human beings, then what is? How does one start to define harm then? Just because nobody is physically injured doesn't mean someone isn't harmed. And just because your opinion isn't the one that has prevailed doesn't mean you should freely act outside of the ideological system for which you had supported to be put in place in the first place.

The lack of basic decency and responsibility in the actions on the part of the comfortably well-fed left is probably the very reason why the basic principles for which the left had stood for, once upon a time ago, are being destroyed piecemeal.

After all, such behaviour can only exist and be tolerated in a political system for which there is little or no repercussion for an individual's actions as long as one asserts that one has done so in the spirit of the ideological system and has not caused harm to others, however dubious such an assertion is. Were it not for the 'evils' of the state and its operators acting on their behalf, these folks would never had been able to do so. They would not be free to live out their pseudo-socialist lifestyles.

So how can one of the comfortably well-fed left truly understand why socialism was necessary one time ago when their pseudo-socialist lifestyles today are supported by a system they are against nominally, but the lifestyle would disappear were the current system really removed as they claim they hope it to be?

It is fundamentally contradictory.

Also, I suppose if one were to go about a critique of the far right, one would likely conclude at the very same point that a critique of the left would arrive at. Both fall under the same umbrella of democracy, and it is not surprising that both are essentially not that different at their polar opposites. Neither the far left or far right are willing to meet at a middle-point in many cases, and hence the radicalism in ideology will precede common sense and be the root and cause of disquiet, which will ultimately harm our fellow human beings.
