Religion is borne out of not knowing what on Earth is the right thing to do, and hence having to adopt a certain approach instead of being convinced by the merits of one over the others: it's policymaking in the absence of facts. Do something for long enough and it becomes a part of who you are (your so-called "worldview"), at which point an attack on the thing is actually an attack on the ego, and we'll naturally and automatically defend it with the same dirty emotional bullshit trickery we use to gloss over all our insecurities.

The toxicity of this is not limited to front-end development, of course -- this is, in fact, the very framework we base modern democracy on. It's just lots of completely unqualified people (myself included) making a great deal of noise based on shitty information, then - once it inevitably goes tits up - we get together and point the finger at some scapegoat to absolve ourselves of liability.

We like to think that as a society we've developed from the primitive peoples of yore, but really all that's happened is that communication tech and industrialism has allowed us to mass produce and saturate our world with the achievements of a very, very select few and thereby create the illusion of universal progress. This entirely baseless pretence is giving unjust confidence to the (figuratively) blind, who are now leading us into a society of completely misguided moral absolutes: one in which local government officials will parent your kids for you with legislation, physicists will be lynchmobbed for the wrong choice of shirt, and Github will outlaw the use of the word 'meritocracy' for fear of intimidating the weak.

So yes, these issues are very important, but HTML and CSS hate games are the least of our worries.
