Ex-member Of A Church to join another church ( all Bible believing churches)

I have noticed that when someone leaves a church to join another church , people start having negative attitude towards him /her. what d'all have to say.

Actually its true that they are being looked at somehow expecially when the two denomination are in the same locality. But actually christians should be allowed to worship were they can flow spiritually, feal welcomed (celebrated) and feal lead to worship. Its should be a personal thing as long as were they are conforms with the bible. However, one should'nt be jumping from one place of worship to the other like a prostitute(permit me to use that word). When u find were u can flow remain and worship God. The ultimate is to make heaven.
