I sometimes think about the idea that different countries/cultures have different levels of what I might call "social development" (as opposed to industrial or technological development).
A country or culture that is tolerant (or just actively does not care about) most aspects of social interaction would rate higher on the scale. If I look back into the history of my own country, I can identify areas where the US has made improvements in social development. Parts of the US attempted to ban jazz around 100 years ago. Later in the 1900s there was pearl-clutching around rock'n'roll as being somehow evil. Changing attitudes toward sex (especially around pre-marital sex, and around how sexual promiscuity is judged differently between men and women) are another measure.
Then there are the things with a strong legal component: the past legality of slavery (and the explicit belief that certain races of people were less "people" than others), denying certain groups at various times access to the ballot box (non-landowners, women, many non-white races). Ballot access is still an issue, even if everyone is theoretically allowed to vote (well, aside from some types of convicted felons, depending on jurisdiction, which is yet another injustice). Then we have discrimination against LGBT folks, including the fact that legal marriage for gay and lesbian couples wasn't universally recognized here until fairly recently.
Some of it is legal, some of it is social/cultural, though of course people's social and cultural attitudes tend to shape law.
So, to me, this ban from Chechnya is just an example of their country/culture being not as far along on the social development scale.
