The mistake most made by members of this community are the use of the words: always, all, every
Secondly, a lack of qualifiers in such expansive statements, because life is messy and there are often exceptions, even if, as the saying goes, "exceptions prove the rule."
Example 1: All swans are white. Response: If I can fine but one black swan, then your assertion, really a hypothesis, has been nullified, or is wrong. Say, your average swan is white.
Example 2: All elections are rigged.
Response: This means that you are saying every election is rigged. Do you really think that the non-partisan off year election for your local community college or library board is rigged? Maybe, but that's fucking moronic. Rather, you should say "all important elections are rigged".
Example 3: All Jews are evil.
Response: All Jews today, or all Jews throughout all of time? Joseph and Mary weren't evil, therefore, your assertion is wrong. Rather, say "modern Judaism is evil as practiced."
We'll go over the ecological fallacy next, which the the second biggest logic mistake made.
False, general statements can be known, because truth can be known.
Example- "there is no such thing as a good cop" true statement
Since all cops are sworn to uphold man's law. And that man's law is created by dark occultist psychopaths to enslave humanity and corrupt Natural Law... Since cops just follow orders from their superiors, and therefore do not exercise their own consciousness when choosing between moral and immoral action and want to abdicate their personal responsibility for their actions... Therefore, ALL cops are unconscious, cowardly, and immoral people. True general statement.
If we don't share the same presuppositions, then you're creating untestable assertions, which is what your example is, and we therefore can never know if it's true or not.
The information is available. Ignorance is not a valid excuse for not understanding. You are able to understand. Even if you are uniformed about my particular example, blanket statements can be made truthfully. Grammar, logic, rhetoric. Get reading
Yea, silly bromides from a silly goose.
Ad hominem... (sigh). No intelligent discussion to be had here
