It's important for priests not to overstep their authority in sermons.
When a sermon appears to be the imposition of a personal opinion rather than a teaching of the truths of the Faith, it can cause a lot of discontent.
A good way to approach controversial topics is to discuss the dangers of something rather than engaging in outright condemnation (when the topic of condemnation is not explicitly covered by Church teachings).
Probably the biggest problem Traditional Catholics have is the problem of youth. There should be more criticism of the public schools and universities, less criticism of young people who wish they could marry but can't afford to. It seems to me there are plenty of parents out there who don't mind if their daughters past 21 are in a sinful courtship, but are outraged at the innocent conduct of their younger daughters. There does seem to be some pharisaical encouragement of parental despotism. In other words, the rights of young people who've passed 18 and are technically in majority are concealed from them. Daughters are raised to believe they must have parental consent to marry, etc. This pharisaical excess will either lead to rebellion or severe discouragement.
