There is no clear answer to this question, as the factors that contributed to Hitler's rise to power were complex and multifaceted. It is important to note that the presence or absence of firearms alone is not likely to have had a significant impact on the rise of Hitler and the Nazi party in Germany.
It's worth noting that there were many Germans who opposed Hitler and the Nazi party, both before and after their rise to power. The factors that allowed Hitler to gain power included a weak and divided political system, economic instability and hardship, the use of propaganda and manipulation, and a range of other factors. It is also important to note that armed resistance against the Nazi regime, while it did occur in some cases, was often met with brutal and overwhelming force by the Nazi government.
In summary, it is difficult to say with certainty whether an armed society could have prevented Hitler's rise to power. The factors that led to the rise of the Nazi party were complex and multifaceted, and the presence or absence of firearms alone is not likely to have had a significant impact on the outcome.
