To those that speak fluent English, he was
clearly joking...To those who do not speak it
fluently, this can be seen as a rude remark.
Micke is not a fluent English speaker - I believe
most of what Micke writes is done through
translation software. When this is translated in
such a way, it is read literally. (Context isn't
understood.) People should keep their audience in
mind when writing something that may be
misconstrued in such a way.
