Many anti-corporate and not-for-profit forms of alternative protest have surfaced in the punk underground, for example, self-made publications known as "zines", where there is greater freedom to discuss controversial (usually far left) political issues such as bigotry, LGBT community issues, feminism, militant atheism, and veganism. Although the mainstream media often views this behavior as a youthful expression of rebellion, modern punk embodies a range of age groups who generally disagree with the perceived shared countercultural principals. It is not uncommon for middle-aged people to form punk houses (houses where people of the punk subculture live and open to others to stay, including touring bands) and resistance movements against what they see as the widespread, unfair use of human and animal rights for profit. This modern group is effectively voiced through the anarcho-punk and crust punk subcultures, in attempt to fight what is seen by those groups as a general of, and way to profit from, life.
