its common for people to refer to truth or portraying reality as it is as something foolish. In law when you claim something false you are estopped from relying on the truth. Its the same with people. Yes, Equivocation isn't lying, it can be very honest, but it can also hurt people greatly.
Lying, telling false truths, presenting what isn't as what is is also wrong more so and sinfully so. People live their lives on what they seem to believe. When we portray a world as it is not we create opportunity to sin. Even by sinning or sinning publicly we create opportunity to sin by lying about the world and about our True nature and what is the swirling essence o' things~
