The problem is not just de-banking. It is also a problem that banks are reporting on customers who purchase legal, but un-PC items like guns, ammunition, bibles or MAGA products. It is the merger of leftist state and leftist corporate power.
Imagine banks being biased toward liberals and doing to them what banks have done to conservatives. The media would be howling mad, demanding investigations and punishment.
More states need to do this. Texas has already started but if the Wokesters at the major banks found themselves shut out of the market in 25-30 states for discriminatory provision of service, it would stop REAL fast.
