Marshmallows are not for Vegetarians

I was searching for the ingredients to make marshmallows and found out that it contains gelatin.
For those who don't know what gelatin is: Gelatin is colorless, flavorless food derived from collagen obtained from various animal body parts. So if some of you are a vegetarian or if you are a person who doesn't eat meat or animals for your own reason. Then I suggest you shouldn't eat marshmallows. 
But as for me it is okay since I eat both vegetables, meat and pastry!!(*^o^*)/
