I’m completely lost. How and when did this become about religious people behaving badly? I am 99.9% sure that the point of the original topic was a commentary on how recent converts tend to be more enthusiastic about their faith than people raised in the church, regardless of what the individual beliefs actually are. The example beliefs from the original post (“feed the poor” and “women shouldn’t drive”) are just examples to help characterize this dichotomy in an amusing way.
In fact, that second example, about women and driving, is almost certainly not an actual Catholic doctrine. Any search for the full phrase leads only to reposts of this image, and I’d wager it was made by just stringing together some Christian buzzwords for humorous effect. While I don’t doubt some Catholics do believe women shouldn’t drive, I also very much doubt they’d use the phrasing and justification found in the original post.
I see where the disconnect is now.
I, and presumably others, associate obsession with religious minutiae with religious fervour. I have a lot first hand experience with this, as some of the most ardent Christians I knew were also the ones who were eyeballs deep in apologetics and church history (and also adult converts). It makes a certain amount of logical sense too, as you wouldn’t expect a casual church-goer to care that much about all that.
With that in mind, it isn’t a big leap to connect the original post to the phenomenon of the zeal of the convert.
What it comes down to, then, is that the original post has more than one layer to it. Rather than focus on the difference between charity and dogmatism, I chose instead to highlight contrast between the simplicity [of charity] and the convolution [of dogmatism]. Once again, my personal experiences informed the way I approached this post.
