I don't see what other defense I'm supposed to put up, there has currently been no other mayor to step up and challenge this position. I've revealed my reasoning for making a potentially bad lynch: on day 1, any lynch is worth the risk since you don't want mafia getting a free day, even though you get a 1/3 chance of actually getting a mafia, that slight chance is still worth the risk provided you don't accidentally kill an important town role like inspector or... mayor! As well, if I were mafia, why would I fake claim a common role like mayor? It would be an instant death if the real mayor stepped up. Because even if the real mayor is lynched Day 1, you're still going to die Day 2 or die to a vigilante. As well, Engineer Pikachu's strategy for a mayor off is prone to Stealth Lynches, if me and the fake mayor each vote on each other, then suddenly two mafia members vote on me last minute, then I die early game. (although this might reveal 2 mafia in the Stealth Lynchers)
Oh yeah, this is only my second mafia game, so I didn't know that revealing mayor on day 1 was a bad idea. Since loudkirbyking revealed himself as village leader day 1 in PMD mafia and proceeded to win the game almost single handedly, even though there actually was another mayor who didn't claim for some reason. So I thought it was a good idea to reveal the role right now so people can't fake it. I guess I'll need bodyguard for now or something.
