That's a pretty broad generalized statement with nothing to back it up. Some would like to attribute any Disney loss to liberal views, but seriously, there are tons of factors. There are plenty of higher income, conservative families still pumping tons of money into Disney. "Anymore" is laughable.
I always point back to a certain conservative group's boycott in the 90s. It lasted all of 5 minutes and they were right back flooding the parks.
We as Americans have short attention spans and typically seem to get in an outrage and then go right back to our same lives. Even me - I am (was) outraged about recent DIS events, but here I am.
