Don't know much about the situation, but I would agree that on the surface this seems to be an excuse to purge an undesirable member from the party.

A self-identified social conservative, Sloan attracted controversy for the policy positions he endorsed throughout the leadership race.[14] Sloan stated that were he elected leader he would permit Conservative MPs to reopen the abortion debate or introduce private member bills aimed at over-turning same sex marriage.[14] He also voiced opposition to Bill C-16, which protects people from discrimination on the basis of gender identity.[15] He also vowed to vote against a federal ban on the pseudoscientific practice of conversion therapy, arguing that parents should be able to make children identify with the body they are born with.[16] Sloan has been widely criticized in the media and even within the Conservative Party for these views.[17][3][18]
