My comment on this thread about a Church controversy regarding a past indigenous massacre (Sand Creek):

I think that most people’s attutides towards massacres (and genocide) of indigenous peoples (or otherwise cultural obliteration) usually vary between flippant and insensitive.

I don’t think harping on guilt for past acts that can’t be changed is very useful, but remembrance along with teaching of what happened is important.

People who feel quite bothered by the horrible history against indigenous peoples can also take action by getting involved with organisations that help indigenous communities or individuals that are alive today.
