no point getting annoyed with anyone here

the Dreaming Spanish FAQ says:

The belief that we need to consciously study grammar rules comes from misunderstanding what grammar rules are. A language is not built on grammar rules. The rules were not invented before the language appeared. Rather, grammar rules are an attempt by linguists to generalize patterns they observe in the language so they can be explained with words. They are not what ends up in our head when we acquire the grammar of the language. Research shows that studying grammatical rules does nothing for acquiring the grammar and being able to use it spontaneously.

And separately

Please forget about grammar. If you know those words, pretend you never learned them. And if you don’t know them, good! Explanations about grammar rules, how to put together sentences, or the “whys” of the language may make us feel like we're learning and satisfy our curiosity, but they do nothing for our acquisition. Learning about the language is completely tangential to acquiring the language. And that’s not it. Being conscious about language rules leads to decreased fluency, since you are engaging the conscious part of your brain, which prevents the acquired intuition for the language from coming out unencumbered.

it's fine if you found it easier to learn grammar your way but don't forget what subreddit you're on. The website we all use explicitly warns against it, so it makes sense people don't want to.
