When the teaching on sex is aberrant (based on asexuality and stoicism, not Christ), when the clergy cooperate with this, often because they are closeted asexuals then the objections are legitimate. Catholicism is a thinking faith, or at least started as one.  Lay theologians often make up where priests used to fill the roles.  Sadly, they had to be filled when Pio Nono and Pius X tried to impose authority onto dialogue and truth, although that sin goes back to Trent.
