Having been stuck fulfilling my Sunday duty at Our Lady of Guadalupe near the convention center I know what you mean about liturgy in your area.  Maybe I should screenshot this and send it to the local clerics.

Some of the doctrines you preach in your private catechism are rather different from orthodox Christian doctrine.  Why preach them at all if the difference does not matter?  But as I see it breakaway sects are always boasting their institutions over the Church.  An oppositional posture and oppositional way of defining themselves drips from their literature, their websites, and (often) in person.  SSPX is like this.  You may not see it because it's like water to a fish.  But every bit of it is the boasting of one institution over another.  And it's why I use the word "sect" as opposed to "denomination" or "church".

Noting that you are promoting a sect is useful in the discussion because what may be OK for a sect may not work for a church or even a mere denomination.
