Procedure; Human Factors
I advised Tower of my position 7 miles to the Northeast of the airport which coincidentally aligns me with the final approach. On my flight path to ZZZ; tower advised me to join over the [VFR waypoint] which was approximately in my 10 o'clock position. At the time I noticed another aircraft on my ADS-B screen at a co-altitude in that area. That aircraft was cleared for the left base. I advised tower that I am in a 6 mile final and that turning would put me head-on with that traffic on the wide left base. Tower controller with an unprofessional manner said that he did not want me on final. I complied with his instructions; and after rolling out on a heading to the [VFR waypoint] I was then forced to execute a hard turn back to the right to avoid a head-on collision with the traffic that I previously pointed out to the controller. The concern that I have here is that this same controller on more than one occasion has given me vectors that conflict with other traffic and at times seems to have a loss of situational awareness.
GA pilot reported an airborne conflict as a result of ATC not providing adequate separation between aircraft.
