Rectal bleeding is never normal and should always be investigated - and a cause found.  Type in rectal bleeding to google and click on one of the many sites.  The Medicinenet site is particularly informative and should provide you with additional insight for your next medical consultation which, in view of your doctor's disinterest, should be with a G.I. specialist.  

The only mitigating factor for your doctor's attitude could be if the cause is minor - such as anal fissure or haemorrhoids - but in that case I would expect the doctor to say "you have an anal fissure...haemorrhoids and there is nothing to worry about".

Unless your (specialist) doctor can offer you a firm diagnosis that the cause is minor I suggest that you request a colonoscopy.
