Is the Conservative Party trying to do the right thing, or serving their own interests?

Joshua Bonehill-Paine is a former neo-Nazi activist who was convicted ten years ago for posting antisemitic material online and racially harassing an MP. He has since renounced his previous views and has worked in counter-extremism education. Do you think it is acceptable or unacceptable for the Conservative to select Bonehill-Paine as a local election candidate?
