...and besides, don’t say the church becomes evil if we leave. It IS evil now. Your response of staying is facilitating it. Have you stopped donating? If not, then YOU are paying for this evil. If you continue to go, you are agreeing to and accepting this evil.
Don't pay a penny into the Diocesan Pipeline (parish - diocese - Vatican) but put money into the specific ministries which are still Catholic and whose funds are not fungible: your school (if it's a good one), Respect Life, St. Vincent de Paul, Prolife Pregnancy Center, wherever real Catholicism is manifested. The local-est, lay-led, grass-rootsier the better.
If you don't who who, what or where, here's the excellent Regina Magazine Safe Spaces for Catholic Money.
No Fear. No Flight.
It's time to fight.
