Although some of the reasons for this rally are Islamic but yet they are against Muslims. Such unhealthy competition. They can't protect their own from realizing the truth no matter how many such rallies they carry out. Truth i.e. Islam will always come out victorious no matter how much it is oppressed.

وَمَن يَبْتَغِ غَيْرَ الْإِسْلَامِ دِينًا فَلَن يُقْبَلَ مِنْهُ وَهُوَ فِي الْآخِرَةِ مِنَ الْخَاسِرِينَ
And whoever desires other than Islam as religion - never will it be accepted from him, and he, in the Hereafter, will be among the losers.
Surah # 3 - Ale Imran - Verse 85
