Thats the problem.
This whole 'rivalry' is a fabrication of West Ham fans. It sits squarly on your side because YOU think we are WANKERS (or worsE). The ONLY way Ive ever known Spurs fans to have issue with West Ham is not as rivals, is not to do with football, its because the fans are cunts. Specifically cunts to us. Thats the only issue, and it doesnt constitute 'rivalry'.
An example.
Some while back I got intoroduced to a guy in a pub by a mutual friend. Got chatting to him and we got along well. He seemed well humoured and quite engaging, the drinks were flowing. At some point he said, almost as an aside, "Who do you support". The very second I told him he started f'ing and blinding and spewing bile and vitriol at me as if I had just tried to slip his wife one in front of him.
Right up to that point we had gotten on brilliantly, very civil, well natured and humourous. From that point his aggression and the filth coming out of his mouth lead us very nearly to blows at which point we got pulled apart and he was kicked out.
I knew he was West Ham all along, but spoke to him politely and with interest all the while he was ok. He knew his football as well so its not like I was patronising him, I enjoyed the conversation.
It was he, and not me, who had the issue here.
