for instance SGI isn't Buddhism, its a Narcissistic personality Cult.. New Kadampa Tradition is criticized about being Buddhist because they Warship a Supra Natural psychotic Demon.. supra natural means the demon was once a person, now a wrathful Deity.. this isn't Buddhism it is Tribal superstition. technically Zen isn't a Buddhist Group,.. i have had some bad experiences with some of them.
Buddhism is 2600 yr's old, there are 3 groups, many sects, many of those have lost the precepts over the Melina due to isolation and close association with tribal superstition.
technically if a persons actions cause others suffering they ate not Buddhists they cant be Buddhists, they may wear the trappings, go thru the motions, but they cant be Buddhists. if they are associated with a particular group, report them to the leadership of that group.
there can be Vast differences between Buddhist groups, the Chinese Pure Land even has a different Buddha, Amataba. you will find different cultural influences between Indonesian, chinese, formosan, tibetan, indian, sir lankan, japanese, burmese
the Four Noble Truths are Buddhism, this defines what Buddhism is, nothing else, all else is how to achieve this. it is based on training the mind to see things as they are, meditation is the primary tool while living a life that causes no more bad karma. and cultivates good karma.
http://www.thebigview.com/buddhism/fourtruths.html1/To live means to suffer, because the human nature is not perfect and neither is the world we live in
2/The origin of suffering is attachment to transient things and the ignorance thereof. Transient things do not only include the physical objects that surround us, but also ideas, and -in a greater sense- all objects of our perception. Ignorance is the lack of understanding of how our mind is attached to impermanent things. The reasons for suffering are desire, passion, ardour, pursuit of wealth and prestige, striving for fame and popularity, or in short: craving and clinging
3/The cessation of suffering can be attained through nirodha. Nirodha means the unmaking of sensual craving and conceptual attachment. The third noble truth expresses the idea that suffering can be ended by attaining dispassion. Nirodha extinguishes all forms of clinging and attachment. This means that suffering can be overcome through human activity, simply by removing the cause of suffering. Attaining and perfecting dispassion is a process of many levels that ultimately results in the state of Nirvana. Nirvana means freedom from all worries, troubles, complexes, fabrications and ideas
4/There is a path to the end of suffering - a gradual path of self-improvement, which is described more detailed in the Eightfold Path. It is the middle way between the two extremes of excessive self-indulgence (hedonism) and excessive self-mortification (asceticism); and it leads to the end of the cycle of rebirth. The latter quality discerns it from other paths which are merely "wandering on the wheel of becoming", because these do not have a final object. The path to the end of suffering can extend over many lifetimes, throughout which every individual rebirth is subject to karmic conditioning
that is all Buddhism is.. a logical statement,
1/suffering is a given
2/suffering has a cause,
3/if it has a cause it has a cure
4/the cure is living a good life while training the mind to overcome attachment/grasping/aversion/negative emotions
people cant be Buddhists and do what you said they did, if they profess to be Buddhists they need to be reported, look up their group on
