Generally ood science/astronomy content, but unfortunately tainted with DEI dogma and recurring leftwing political bias…. Could use a bit more “diversity” and “inclusion” when it comes to worldviews and obvious bias.

Canadaa month ago - Casey Dreier & Mary Guenther
These 2 people are out of touch with Middle America and have no clue of anything that happens here. People are poor, people have lost everything, people are scared and people are dying. Billionaires have taken over our country and these two don’t seem to get it or even care. Stop robbing from all the poor Americans and giving our cash to the wealthiest Americans.
P.S. Poor people don’t do polling, so please don’t give us the polling numbers from now on.
