There's an obvious distinction here.
They're not the same thing at all.
Most people understand that the best way to make progress in NI is to reach out to the "other side". To be fair SF, lesser extent Alliance and even SDLP do that regularly. UUP try their best occasionally. DUP don't bother.
You can't claim to want to be an SF FM for all in NI or an Executive minister for all in NI and not think across the 2 traditions. Hence he went to a jubilee event and O'Neill wrote to the Queen.
That's a world away from the celebrating the partition of our country. There was never a legitimate claim to Ireland other than our own. Under threat of terrible war we agreed to the partition of Ireland despite in 1918 73 of 105 seats across the island in favour of independence. To celebrate that would be accepting its legitimacy.
In 98 we voted for peace. We voted to accept that the partition of our island, imposed under threat of war, would remain until the majority said otherwise. As we have been discussing that might happen in 10 or 20 years or as others have said it might never happen. It doesn't mean the partition of our island is any more legitimate. It just means ending partition can only be done through democratic and peaceful means.
The 2 things are perfectly consistent unless you have a particular view of SF.
