There should be boundaries to what is considered respectable opinions that exclude both the extreme right and the extreme left. If people do not express these off-limits opinions they should be considered respectable and treated as such in discussions. An example of off-limits extreme right opinion is anything promoting racial or ethnic inferiority of one group or another. An example of off-limits extreme left opinion would be attempts to stake all differences in society on discrimination. Anything less extreme than that should be considered fair game in the market of ideas. The extreme left and right ideologies have cost tens of millions of people their lives in the twentieth century and should not be considered respectable. Anything less extreme might, depending on the circumstances, actually be a solution to some problem that is right now occurring somewhere in the world and should at least be considered.
