Perhaps, although I'd stil be interested in hearing why you think that is. I can't think of any examples of people moving right because the left was too nice.
My observation has been that orthodoxy and too many causes has alienated a lot of people that were traditionally aligned with the left.
In the UK a recent example would be the collapse of the red wall. Constituencies that had been held by Labour for up to ~80 years flipped. A key factor was that the working class in the area felt that Labour was no longer interested in representing them, with the focus having shifted to social justice and right wing press latching onto this as an angle of attack.
