For example, when some people in high positions enjoy privileges, politicians will defend them by talking about their contributions, and the topic shifts from privileges to contributions. Similarly, when a few bad people emerge from a certain ethnic group, politicians will constantly emphasize these few bad people to negate the entire ethnic group and call for action against the group. The most crucial factors should be whether contributions and privileges are commensurate, and the degree of correlation between the ethnic group and individual events. But nobody discusses this.
Even when I'm on one side of the argument, it's just as frustrating to hear my own side just move on to their next pre-written question/response instead of engaging with the underlying issues. I want substantive debate and discussion and possibly consensus, but that's sadly not the reality in most cases of import.
