+					<quotation>Please don't raise unrelated political issues in GNU Project discussions, because they are off-topic. The only political positions that the GNU Project endorses are (1) that users should have control of their own computing (for instance, through free software) and (2) supporting basic human rights in computing. We don't require you as a contributor to agree with these two points, but you do need to accept that our decisions will be based on them.</quotation>
