Don't let an improvement not being perfect prevent any improvements from happening.
I strongly agree. I often hear this type of argument and it appears to me as just another kind of Nirvana Fallacy.
Think historically - would you really want the tyranny of the majority in the 1960s? 1920s? It's my opinion that minorities deserve a place at the table.
Do you think we didn't have that? It took a LOT of protesting and lobbying and effort to get changes made in the US, more than in many other nations which, say, didn't need civil wars to end slavery.
We had to change the majority to get those things, and while it's sad that the majority didn't move faster (and that's a different problem), now we have problems created by groups that can't even command a majority of the population being able to set policy.
