What you need is for a couple of buttons for people to identify themselves before they reach the mission statement. One could say 'I am Syrian Orthodox' and the other 'I belong to a different Orthodox community' and then have two different mission statements with the site showing whichever one is appropriate.
Being serious, it is very sad that this issue remains unresolved. The fact that the Ethiopian situation with relation to the Coptic Church has been recently smoothed over, and in our own experience here in the UK we have witnessed Ethiopian and Eritrean Orthodox worshipping together, shows that these matters can and should be sorted out. And in the town where we worship there seems to be intercommunion of all Indians who are more concerned with supporting each other here than supporting controversy back home.
But isn't it the same with all dialogue? With the one between the EO and OO for instance. The whole situation surely could be resolved if some bishops were locked in a room and told they weren't coming out until they had dealt with the issue. Both the EO/OO one and the Orthodox in India.
