Right. Your links were:
1. The link to the homepage of the faculty of English (their capitals, slavish followers) for Oxford University, so their entire website.
2. The home page of the Plain English (their capitals, slavish followers) campaign, so their entire website.
Which parts of those entire websites will show me some of the "many" that think, like you, that the word "English" should not be capitalised.
Point me in the direction of the "many".
