So I think that by-and-large, the Evangelicals have had a crisis of faith and are seeking the US Catholic Church as a bastion of stability. And the US Catholic Church has been happy to accept Evangelicals into our flock, because we're all Christian here and spreading our religion is what we do.
This has become somewhat of a devil's deal however, as the Evangelicals have pushed the Church extremely rightward politically. Historically, the Catholic Church has been very pro-Latino, because the Hispanic community / immigrants are overwhelmingly Catholic (not just "Christian", but proper Catholics born and raised). But in the past 10 years or so I'm seeing more and more former-Evangelicals bring their politics into the Catholic tradition.
Nominally, this crap shouldn't matter to the issues of Church. But it does. Politics infects all wakes of life one way or the other.
In any case, I think its a good thing that (former) Evangelicals have migrated over to the Catholic church in such large numbers that this problem is occurring. And I'm not necessarily saying that we need to 'indoctrinate' our (former) Evangelicals to the policies or politics of the Catholics... but... maybe a little bit? I dunno. But a lot of these far-right rhetoric / fire and brimstone style religion (with anti-immigration / anti-Hispanic slants) is distinctly non-Catholic and heretical IMO.
Case in point: we Catholics finally have a 2nd president of our Faith: Joe Biden. And yet, the Catholic community was THIS close to excommunicating him. Rather than celebrate our achievement to get our 2nd president into the office, he is seen as a heretic to (half) of the US Catholic Community.
