The whole Declaration of Sentiments treats all men as having one single behavior and treats all men as he.
Which is both considered a fallacy of association
1. X is true for A
2. A is a man
3. B is a man, therefore, X is true for B
and mostly, a Hasty Generalization, which consists the following reasoning:
1. X is true for A
2. X is true for B
3. Therefore, X is true for C, D, E...
Both are logical fallacies and untrue.
The first one is clearly flawed since B being a man doesn't mean that X is true for B. Same logic is followed in to debunk the other fallacy since the truth can be a different one for each individual.
