Hypothetical situation
Ahmed is at his favorite restaurant, hanging out with his buddies after a hard day's  work. It's an eatery he and his pals have frequented for years, due to its great  food, convenient location, and inviting atmosphere. They all love the place because it gives them the opportunity to unwind, relax, interact with  old friends and get acquainted with new ones. Everyone is happy until one  day an old nemesis of Ahmed decides to shake things up a little. He  approaches the management, informing them that he and a group of friends want to host a  bash at the restaurant, with the theme being: "Everybody Insult Ahmed's  Mother Day," where all of the guests at the party will be encouraged to think of different creative ways to insult Ahmed's  mother. Astonishingly, the management grants this request, and allows the restaurant to be used  as the venue for this event.  
In your opinion, what should Ahmed do: 
A.  Continue to be a loyal patron of the restaurant, as if nothing happened 
B.  Boycott the restaurant only on the day of the event, and resume being a regular customer thereafter 
C.  Permanently cut off all ties with the restaurant in protest of allowing such an uncouth and revolting event to  take place  
If Ahmed chooses "A" or "B", what does that say about the level of love and respect he has for his mother?  Would anyone in their right mind continue to visit to a place that allowed this offense at such a personal level? 
Now let's flip the switch from hypothetical to real.  "The restaurant" is facebook, "Ahmed" is every Muslim on facebook, and it is not anyone's mother who was insulted,  rather it is someone whom we must love more than our mother, our father, our children, and ourselves – the Messenger of Allah (peace and blessings of  Allah be upon him).  
Alhamdu Lillah, a number of Muslims deactivated their facebook accounts due to this event, and I ask Allah  to reward them for that.  What bothers me, however, is the staggering  number of Muslims whose love for facebook is so intense, that the farthest they  are willing to go is to shun facebook for one day, resuming its use thereafter.  A lot of these same people were firmly resolute in  boycotting Danish products when the original cartoons were published in 2006, but  they are unwilling to deal the same blow to facebook that they dealt to the  Danish economy.  Why is that?  
Abandoning the purchase of goods made in Denmark was something that was  commendable, but at the same time it was easy to do and caused minimal hardship, if any at  all.  "Oh, Andersen's chocolate ice cream is Danish?  No problem, we'll just switch to Breyer's."  Alhamdu Lillah it was effortless and painless to forsake Danish goods, due to easily available alternatives.  But the words "effortless" and "painless" cannot share the stage with the word "sacrifice."  And that is the fundamental difference between the amply participated in, highly successful campaign against Danish products, and the half-hearted calls for a mere 24 hour  boycott of facebook.  The former required no real sacrifice, whereas the latter does.  And when one is forced to choose between making a sacrifice or  not, he cannot hide where his loyalties lie. 
Unfortunately,  facebook has become an addiction to so many people, Muslims included, and quitting it cold  turkey is not a simple task for everyone.  But if someone fears Allah, and truly loves His Messenger (peace and blessings of Allah be upon him) Allah  will make his matters easy.
May Allah give us the Iman and strength to stand up for Islam, no matter what sacrifices that may entail.
