Tasha's lineage, nor the other parts of the book that are power leap, is no "personal experience". That is quite literally "black and white". And yes, Tasha's Lineage mechanics are a direct result of threads like this.The slippery slope is generally classified as a logical fallacy. The logic isn't sound, because there's no logic, per se. There is a chain of scenarios that one asserts will happen with significant probability, but without support for the assertion, or source for probabilities. Fear or anxiety of the end state is used to motivate the audience to accept the assertion, without substantial support.
Your personal experience is anecdote, not data, and so isn't significant support in this situation.
