My question is: do we (do you) support clericalism when its advantageous? 

Call to holiness is rooted in baptism and has nothing to do with ordination. Ordination has a very limited purpose: to ordain for presidency, 'in persona Christi' and not in one's name, at gatherings where the People of God are gathered in prayer. And the 'in persona Christie' highlights the fact that the efficacy of the gathered community's prayer consists solely in Christ praying in and with the community, and inspite the person of the ordained presider.

There is no evidence whatsoever, that other denominations, similar institutions or society in general is less prone to the crime of child sexual abuse than the Church. Unless we find the real causes to this plague, as opposed to appointing some according to our political biases, nothing will change. 

BTW, as you know, since the mid nineties, new cases of sexual abuse by clergy in North America is close to zero.
