Some Christians considered heresy a significant threat because it challenged the core tenets of their faith and could lead to division within the community. Heretical beliefs often undermined established doctrines, creating confusion and potentially leading followers away from orthodox teachings. Additionally, in a time when the Church sought to unify believers under a common set of beliefs, heresy was seen as a direct threat to the stability and authority of the Church. This fear of fragmentation and loss of control over religious interpretation fueled strong reactions against heretical ideas.
Because Christians believe anything before them is incomplete and uncivilised (primal) and anything after them is heresy.
Well, that depends on what Christians you are talking about, but if it was within the church it would be a threat just like it was a threat to the United States to have half of the country believing in slavery, and half not. Heresy is just non-traditional belief, and It tore them apart, and opposing beliefs can tear any group apart if there is no appeal to a higher authority or ultimate truth... luckily, in Christianity, there is. Heresy, if it is going against God's revealed will, would be rejected because it is untrue, and threatens the unity of the church. As indeed it already did in the early church, as shown by all of the splinter churches that came into being trying to fight the heresy that had grown within the main body. Heresy still threatens groups and society today. We have political parties which accuse each other of heresy, as well as fringe groups that like to espouse "heretical" beliefs like racism or child pornography, or whatever it is... and they threaten the peace and the status quo of society. Everyone is threatened by some kind of heresy. It just depends on what beliefs you find traditional, and which ones you want to change.
Because universalism is a heresy that believes that hell, at worse, is a kind of purgatory and that everyone will eventually be in heaven. It is a heresy that has been condemned by the Church, so no Catholic would consider themselves a universalist while remaining a Catholic.
Jehovah's Witnesses consider themselves Christians although this is a subject of some debate among theologians.

Roman Catholic AnswerThere are none, as Christians are Catholics and vice-versa. There are however some Christians who are not visible members of the Catholic Church. These are people who have received valid baptism and believe in the Nicene Creed in its traditional interpretation. Someone who has different beliefs from Catholicism is known as a heretic, although if they were raised knowing no better, then the heresy would only be formal; although they were raised believing that they were Christians.
Cougars are hunted for sport and killed because some people consider them a threat to livestock. Rarely one will be killed because it is considered a public safety threat.
Roman Catholic AnswerThe only split possible for Christians is to "split" into heresy, apostasy, or schism. In the first case, they deny some aspect of the faith such as protestants, in the second case, they deny the faith entirely, such as modern pagans; and in the third case, they deny the supremacy of Peter, such as the Orthodox.
Yes, it is a noun. Heresy is a crime (sin) against the established church, such as failing to accept some doctrine that is espoused by the church.
