Is a fear of snakes irrational, though? Because I have a HUGE phobia of snakes, but if phobia is irrational fear, I'm confused. I thought snakes were dangerous, can poison or suffocate...? So it's rational to be nothing less than wary of them, surely?
And a fear of sick is pretty rational, too. I don't have a sick phobia, but I don't enjoy it and certainly worry if I feel I might be sick.
I will annoy some people here by saying I haven't read the whole thread, or in fact anything past, ermmm, the OP - I'm supposed to be studying - but phobias are very real and very hard to deal with. Mine is snakes. Others have phobias of clowns; my friend hates balloons. Usually triggered by something that has happened in childhood or early adulthood, sometimes even later on.
Having said that, I think wanting a thread to disappear because you have a phobia of something mentioned in the title, is probably a bit off. Should I avoid the pets section because of my phobia? I can see how the word would give an image of sick/being sick and may even remind the person of the feeling, but there are other boards here. Everyone has a different phobia, and how is every poster here supposed to cater for every phobia - like clowns - 'I booked a clown for my DD's bday party and it was rubbish. AIBU to want my money back?', may put people off with a clown phobia, but we come across our phobias every day in life; it's unavoidable.
Unfortunately, I don't know the solution. Just don't look at the word too long. But don't avoid MN.
