That is a specious argument and you know it. Those that purport that the scandal is either exclusively Catholic or an officially sponsored Catholic Church activity are guilty of denial and are therefore complicit in the continued abuse of children within their own denominations. Those legitimately concerned for the victims do not obsess over one group of perpetrators while turning a blind eye to others unless their real agenda is the demise of the Catholic Church and not the plight of all victims of abuse.
Discuss the issues all you want, but do not make it personal.
