Hey Sakura,
Good question for a first topic, though I'm not sure where to start! I'll stick to being hateful about something you may wish to criticise. Let's first define what we mean by hatred. Thefreedictionary.com gives the definition "Intense animosity or hostility". I wouldn't have thought it is necessarily a problem if you feel intense animosity or hostility against something you wish to critisise, in fact that strength of emotion may provide the motivation to set about combating that against which you feel so strongly. It may drive you to spend hours researching the subject, perfecting your arguments or exposing flaws in the arguments of the subject's proponents.
However, there are a few issues worthy of consideration. Firstly, if you hate something, does the strength of emotion make it more difficult to view the subject in question objectively? Are you likely to make a fair assessment of the potential target of criticism? Maybe not. As with all emotions, whilst it may be utilised with good effect, it is always worth trying to step back from hatred and anger to consider your position with the greater sense of perspective that a calm mind brings. It can be very easy to become enraged by someone's inability to consider the views of others, so enraged that we too develop that same inability. It is tragic to become that which you hate. Then, there is the issue of your well-being. Is the hatred a transient state used to seek a solution to the identified problem, or does it become a chronic state of mind? If the latter, you are at risk of letting your emotions devour you, and of course the perceived problem that has aroused your ire in the first place remains unresolved. Also worthy of consideration, what is the effect of appearing hateful whilst arguing your case to others? Passion and emotion can, when rightly utilised, be very effective in persuading others. However, wild, unrestrained hatred and bitterness can really distract and detract from an argument, even if the points made are otherwise valid.
Just a few thoughts. Maybe you'd like to limit the question a little...or maybe you'd just like to see where people's musings take us, in which case its open-ended nature is just perfect
