Well, it depends on how you define 'appropriate'. In general, content with abuse in a romance setting can be quite dark and not in line with the mainstream idea of a healthy relationship. It might not be appropriate for a wide - ranging audience as it could be triggering or send the wrong message about relationships. However, in some more mature or niche audiences who are aware of the fictional and often subversive nature of fanfiction, they might be more accepting, but still, it's a very grey area.
One negative impact is that it can distort the perception of healthy relationships. Since Ron and Harry are well - known characters, presenting an abusive 'romance' between them can give readers the wrong idea about how relationships should be. Another impact is that it can be emotionally disturbing for some readers, especially those who have experienced abuse or are sensitive to such themes.
Friendship as a foundation is also a big theme. Their existing strong friendship in the original story serves as a base for the romantic relationship in the fanfiction. It shows how a deep friendship can evolve into love, with all the trust and understanding that they already had as friends being carried over into their new romantic dynamic.
You can start by looking on fanfiction websites like Archive of Our Own (AO3). It has a large collection of fan - made stories, including many about Harry and Ron's romance. Another place is FanFiction.net, which also has a good number of such stories. Just use the search function on these sites and type in 'Harry and Ron romance' to find relevant fanfictions.
One popular Harry and Ron romance fanfiction is 'The Unspoken Bond'. It beautifully explores their relationship in a way that's both heartwarming and true to their characters. Another one could be 'Ron and Harry: A Different Kind of Magic' which delves deep into how their friendship could potentially turn into something more romantic over time. There's also 'Hidden Feelings' which is known for its detailed descriptions of their growing affection for each other.
Ron might be shocked at first. He could become very protective of Harry, standing up for him against any potential threats. Maybe he would also be a bit angry that he hadn't noticed earlier.
Snape could be the voice of reason. He might see the potential chaos and damage that a romantic relationship between Ron and Harry could cause, not only to their friendship but also to the whole Hogwarts dynamic. So he steps in to prevent it.
I'm not sure if 'harry abuse fanfiction' is particularly popular. While there are many different niches within the vast world of Harry Potter fanfiction, the idea of focusing on Harry's abuse might be a rather niche and darker topic that may not appeal to the mainstream fans of the series who are more drawn to the positive, magical elements.
One popular 'Harry and Ron gay romance fanfiction' is 'The Lightning Letters'. It beautifully explores their relationship in a new light, with great character development.
Most of the fanfiction in the Harry Potter universe focuses on positive relationships and adventures. The idea of Ron abusing Harry in a romantic context is quite disturbing. There may be some very niche and perhaps disturbing fanfictions out there that might touch on this, but I would not recommend seeking them out. Fanfiction should generally enhance the positive aspects of the original story, not introduce such negative and out - of - character concepts.
