You can't really use the century thing, most western organisations had views which most progressives would view as abhorrent today.

Section 28 in the UK was only 40 years ago, when the UK government was descriminating, and only repealed less than 20 years ago. When you put the beside your 150 years, you're coming across as lacking in even a basic understanding of history.

Attitudes change. And those attitudes changed only very recently for almost the whole of the western world.
