In summary, if a generator is connected to a standard household male-type plug but with the positive and negative terminals switched, it is possible for the generator to run other appliances in the house. However, this is dangerous and can cause harm to anyone using the appliances if not done correctly and if there is no connection to the utility power.

...But had the positive and negative terminals of the plug switched, could the generator run the other appliances in my house if I just plugged it into the wall?

AC power doesn't have positive and negative, it has hot and neutral, but in any case, a generator gets connected so that its hot matches the hot of what it is serving. Some appliances care about that, some don't.

Technically Yes - but this is dangerous, not just for the person doing the connections, but everyone that then uses the appliances in the house if this is not done correctly - and then guaranteeing that there is no connection to the Utility
