Another joked: "I hope it was halal!" and a third said: "Officially they combat globalisation, standardisation etc and defend local regions! Huge joke!"
Philippot, often a target for the party's most extreme supporters, responded by condemning the criticism as "crassly stupid" and "poisonous" for the National Front .
Those loyal to Le Pen accuse his backers of trying to oust her as the party leader.
Formerly unchallenged and idolised by supporters, the daughter of Jean-Marie Le Pen, the National Front founder, now faces increasing discontent in the ranks.
The upset has thrown the party into an unprecedented crisis.
"It's gone from adoration to loathing," said a disconcerted party official in Le Pen's parliamentary constituency in the Pas-de-Calais department.
Leading party figures have been arguing over policy, pushing supporters into the paths of other political parties.
National Front officials say the disputes are causing some supporters to transfer allegiance to the far-Left party of Jean-Luc Melenchon, who is emerging as the main leader of the opposition to Emmanuel Macron, the centrist president.
Like Le Pen, Melenchon is a populist who distrusts the EU and says that, if elected, he would hold a referendum on leaving the bloc unless it agreed to sweeping reforms.
