It's just ridiculous on so many different levels it's hard to even respond. Beyond the systemic, historic inequality part of it, there's also that the vast majority of men are not landlord, business people or military personnel. Men are everything - doctors, lawyers, teachers, bus and taxi drivers, food delivery guys, janitors, waiters, engineers, you name it. So the idea that say, a store clerk is thinking to himself, "the government isn't being nice enough to my landlord, and since the my landlord is male (as are many other landlords), and I am also male, therefore I should vote for a government that will coddle my landlord.
And even the basic premise that the government isn't "respecting" those sectors of society is pretty shaky. For instance, the current housing crisis is absolutely wonderful for landlords because it has driven up prices so substantially. Yes in some jurisdictions there are regulations that limit how much rents can be increased. But even so, having a low vacancy rate greatly benefits landlords because they can pick and choose exactly who they want to lease to, don't lose money due to periods of vacancy, and don't need to spend much on advertising, promotions or incentives to attract renters, etc.
