Is intolerance of intolerance, intolerance?

The answer depends on one's convenience.
We are quick either to condemn or to support, both in my opinion are bad.
For a moment let's forget intolerance, think about tolerance. This itself is such an ugly word and its meaning is so negative.
We need to respect not tolerate.

Tolerance is always limited and this limit can be breached at any time for any reason, even the most idiotic and frivolous one.
Anyone who tolerates is abiding time until he, she or they cannot or will not tolerate anymore.

Tolerance is a negative term, and intolerance which is born out of the inability or unwillingness to tolerate is even more negative.
Tolerance is a simmering of discontent, and its offspring intolerance always leads to conflict and destruction.

Respect on the other hand is a positive emotion and attitude.
It sees the good in the other and hence a desire to yield space and energy, to cooperate and to share. Respect leads to flowering of relationships.

It is better to talk about, respect rather than tolerance and intolerance.
