you're actually ignoring a lot of British practices with that assertion. first of all, the 1833 act outlawed the slave TRADE, not slavery. secondly, it exempted, among others, the East India trading Company. Thirdly, Britain's reliance on indentured servitude of Indian and Chinese people, began as a result of outlawing traffic in African bodies, was equally abusive, and continued into the 20th century, as did practices like blackbirding, which British merchants participated in. Fourth, the exploitation of the Irish continued well after 1833. Your knowledge of history doesn't fit the narrative- check wikipedia.
