Kind of:
I mean, how did the Catholic Church grow to include one out of every four Americans, if there was so much intolerance of them?
That's like saying "how did Blacks grow to be one out of every seven Americans if there was so much intolerance of them?" ... population demographics and growth have literally nothing to do with whether or not that subset of society experiences discrimination. For example, there are parts of the Muslim world where the "Shia" minority might be 30%+ but they're discriminated against by the "Sunni" majority (I'm pulling the labels/numbers out of my ass for the moment because I don't have time to look up exact percentages and who is in power where but the point stands).
It makes more sense that there were isolated incidents, and also (perhaps) short periods of time, when the Catholic Church was out of favor. But I just don't see how an institution that was the target of so much intolerance grew to be what the Catholic Church is today.
No. That does not make more sense, at all. Please, at minimum, read the wikipedia link I provided. What you just said is historically inaccurate.
From the 1600s until around 1940 there was widespread, active, and serious discrimination against Catholics in the United States (and the preceding colonies). It's well documented in multiple sources. It's also the entire reason why Maryland acted as a "haven" for Catholics... why the heck would you need a "haven" if Catholics were welcome everywhere?
Pre WWII Catholics (and specifically Catholic immigrants) were actively discriminated against and stereotyped. The KKK had Catholics as target 1B if Blacks were target 1A. This is not an exaggeration, and there is quite a bit of history with the Klan clashing with Notre Dame in Indiana in a time when the vast majority of males in Indiana were Klan members.
Post WWII Catholic discrimination started going away in a hurry. Over the next 4 decades it basically be came a specter of the past. But for 350ish years it was the norm.
And a few signs about "No (insert particular group here) need apply" is probably more indicative of humor through hyperbole, than any actual long term intolerance.
Disagree but whatever... sure, let's just table anecdotes because they're irrelevant. It sure as fuck isn't indicative of "humor through hyperbole" but it's really not worth getting into.
We don't have a perfect history by any stretch of the imagination. But the American flag is NOT a symbol of repression to anyone other than those malcontents who want everyone to listen to what they have to say.
No, it's certainly not. It's a symbol of a lot of things but it's quite a leap to make it a symbol of "repression," period.
