[Bear holding a shark]

People of any religion who try to press it upon you often going against the roots of their belief.
For example, it's not Christian's place to barrage people into believing in Christ. They should instead lead by example, trusting in God to do the rest.

But this is too little the case. Every religion basically looks to "unbelievers" as recruits, instead of a lost soul.

So like Carnealse said, the human aspect often ruins religion. For them and for the people they are trying to reach.

Just lead by example, and if you're sincere people will catch on.
