Participating In Religious Festivals Of Other Religions
If your polytheist friend attends your Eid party would you automatically consider him a Muslim? Would he himself consider himself a Muslim? Would the society consider him a Muslim? In my experience that’s never the case. Also in my experience Christmas parties are generally just joyous occasions often attended by people of different religions without any implicit or explicit acceptance of Jesus as the son of God.

No my argument is practical consent. Because they don’t know what’s in your heart they will only see what you are practically doing.So if for example eid milad ul Nabi SAW,if we take that as a bid’at,but if i will be a part of that celebration practically (but in my heart i take it as an innovation in Islam(bid’at)) but practically i am with so practically i am giving consent that this is a good thing and i am with you in that and it is not bid’at.
