You have a valid point.
The difference between evangelical Protestants and traditional Roman Catholics on this issue has been obscured by the massive collapse of marriage in America — and that is not just a Protestant problem, unfortunately. Easy annulments are not exactly unheard of in Roman Catholic circles, though to the credit of Catholics, at least they have maintained a stronger stance on the importance of marriage.
While there are differences about whether marriage is a sacrament and about remarriage after a biblically legitimate divorce (which basically means adultery) the gross tolerance of easy divorce and remarriage is an evangelical scandal.
One of the few good things I can say about evangelical churches on this issue is that the more seriously a denomination or local church takes doctrine, the more likely it is to have a strong emphasis on why divorce is wrong. It's the “loosey goosey” evangelical megachurches and their wannabee little brothers — the types of churches that are more likely to emphasize fun youth groups and loud music, and more likely to offer deep rich cocoa-flavored coffee than deep biblical exegesis from the pulpit — which are not demanding high standards in many areas of people's personal lives.
That problem of low standards for membership and discipleship is bigger than marriage, though it certainly is a big part of the bad fruit brought about by low standards and lack of church discipline.
I totally agree. Many churches today are more interested in pleasing the masses than God.
