I've tried for some time to understand just what might be the driving force behind their beliefs and behavior and realize that the answer isn't really that complicated. To wit:
Quite a few are lazy - and quite pompous about it. They justify their laziness to themselves by imperiously proclaiming that the actions that they eschew (voting, boycotts, prolife activism, etc) are at best a waste of their oh-so-precious time and at worst a compromise of the One True Faith. In other words, pride comes into play as they mock us from their insular conclaves.
Yep! Why else would they put down the efforts of other Catholics, pretending that those efforts aren't good enough? Why else would they mock President Trump non-stop without uttering a peep about those Democrats who are openly against God, life, family, human freedom, etc? They mock our efforts to justify their own unwillingness to get off their duffs and do something.
I've even heard one of them mock pro-life action as "prolifeism" as though our efforts constituted a form of idolatry against the One True Faith. Their big beef is that many of us in the pro-life movement work alongside non-Catholics. Well, so what? When they get off their rears and join the effort, maybe they will have some room to talk - that is, if they don't learn to appreciate the contributions of non-Catholic people. To paraphrase one pro-life leader, I like what some non-Catholics are doing better than what some "rad-trads" aren't doing.
I recently was involved in a facebook discussion with some of these individuals, with the topic revolving around the intentions of some Catholics to boycott Netflix because of their portrayal of Jesus as a homosexual pervert. The boycott effort was - of course - belittled by these "rad-trads". Here's an interesting snippet.
Two of them are conversing here. Now why on earth to they pretend that we hold boycotts to be sacraments, of all things?
As I write this, news comes to us that the House just voted to impeach President Trump on very specious pretenses. It is reasonable to believe that the absent Catholic vote in 2018 is largely to blame for putting the Dems back in control of the House. Shall we now pray that the GOP in the Senate has the wisdom and courage to do the right thing?
Moreover, in 2020 elections will be upon us. We've already suffered through enough Democrat debates to know that whoever is the victor will usher in baby slaughter, gay agendas, transgenders, you name it. We will have to get involved (if we aren't already). When we hear our very confused rad-trads spout their non-voting crap, well, let's recall that "rebuke the sinner" is a Spiritual Work of Mercy.
