While many on the left believe that the criminal justice system has structural inequities that need to be addressed, few on the left would adhere to the position that past conviction of a crime is categorically unacceptable basis for discrimination (though they might agree that particular instances of it exceed what is warranted.)
So, I don't think this works as a blanket statement.

Most on the right would not, IME, support the position that freedom cannot be restricted based on past conviction of a crime. So I don't think this works as a blanket statement either.
