How to identify (and avoid) verbiage that triggers the "community guidelines"

I attempted to post the following in the comments section on msn.com news, which triggered the "doesn't meet the community guidelines" response. Can anyone point out the word or phrase that might insult someone or is somehow not acceptable? I have not altered or left out anything.

" Hiram Walker distilled his whiskey and vinegar in  Detroit, Michigan.  Before the Civil War, he moved his operation across the Detroit River to farmland that became Walkerville, Ontario. Canada, where he built his whisky distillery where his Canadian Club whisky is produced to this day, but under different ownership.  He never gave up his US citizenship and although he had a home near the distillery, he preferred living in Detroit.  I still like CC&Water, with a twist."
