Some protestant ministers support homosexual unions, some have stolen hundreds of thousands of dollars. Some pseudo christians come on these threads to say stupid things, over and over with no proof.
You are correct there are corrupt “shepherds” in other Christian denominations and assemblies. I can only speak for my denomination which has elders. No one man wields absolute power. The elders AND laity using Matthew 18 and 1 Corinthians 5, will remove offenders. They are no longer allowed to fellowship and obeying civil law will report the matter. The same scriptures tell us how to welcome back a repentant sinner.
No one is claiming there is a perfect spotless assembly out there. I will also note that clergy or elders/overseers in most other Christian denominations are not figures who are deemed by their church to give absolution or preside over the Holy sacraments to include calling upon the elements to change.
