How do counter-cultures typically influence mainstream culture over time?

Counter-cultures are groups that reject the norms and values of mainstream society, often promoting different ideas about life, art, and social issues. Over time, these counter-cultures can influence the mainstream culture by introducing new ways of thinking and behaving that some people find appealing. For example, the hippie movement in the 1960s challenged traditional views on peace, love, and personal freedom, and elements of this movement, like music festivals and environmental awareness, eventually became widely accepted in society. As more people adopt ideas from a counter-culture, the boundaries between it and the mainstream can blur, leading to changes in fashion, language, and even politics. This process shows how cultural change can happen gradually, as new ideas become part of everyday life.
