> I did it in July, but then I noticed that a lot of social activities - like concerts, festivals, parties, etc, are organised using Facebook so if you're not on it, you can't participate.

They are organised this way because it is an effective way to organise them; so the only sure way to stop them being organised this way is to make it ineffective (by not participating, by urging others not to do so, and, crucially, by making your reasons known to the organisers). It is true that not using Facebook is an inconvenience, but there is no guarantee of a right to protest without inconvenience!
