If someone gives advice that's worded as "when no better options are available, [solution] is the best option", it means that doing that particular solution is better than not doing anything. It does not mean that this solution is better than all other options, best choice at all times. All the better options that you can think of that a person should do instead are already implied to be unavailable in the "when no better options are available"-part.

When something is stated in past tense, that implies that this thing is no longer this way at the current moment. "Past tense" means that it happens in the past, which implies that it has stopped happening. If someone says "I thought myself well-educated on the subject", the past tense implies that they are now aware that they were not, in fact, well-educated on the subject. You do not need to tell them this.

A person saying something in passive tense is not stating that they personally do or believe whatever the statement is. Saying "at one point, it was thought", means that there has been, at some point, unnamed other people, who thought this thing, and therefore this has a distinct nuance difference to "I think", which means that the person saying this is also the one thinking it.

The words "common", "most" and "the average" refer to a majority of a population, but not the whole population. That is a different thing than "all" and "everything". If someone says "most dogs have four legs", but you know two dogs who have three legs each, saying so does not disprove the previous person's point, as "most" is a different word than "all". It's a different word that changes what the sentence means.

When someone says a sentence, you should always assume that every word in it is important for the context. If you don't know what a word means, you should look it up to find out what it means, instead of skipping over it and assuming that it isn't important. "Strict and irreconcilable parenting styles are inherently traumatic" means a different thing than "strict parenting styles are inherently traumatic". Adding or removing one word can sometimes change the whole sentence, and you can't just skip the ones that you don't know.
