-Soda without sugar...
Cookies without fat...
Sex without touching...
A Left without critical analysis of...anything.
[WS:] Touching clearly does not belong here. Sugar, fat, and kvetching are bad for you - but touching is good for you. Besides, there is a big difference between kvetching as a throat clearing before saying something constructive, and kvetching as the main activity.
For example: If you said that housing discrimination is a bad thing in your preamble to t a proposal for housing cooperatives owned and managed by residents as an alternative to the current housing arrangement - that would be constructive kvetching. If, otoh, you kept ranting about housing discrimination for an extended period of time without offering any constructive alternative to the status quo - that would be the kvetching that is an equivalent of sugar in soda or fat in cookies - calories that give adrenaline rush without any nutritional value.
