"...even a bottom-feeding lawyer..."
The word "bigot" implies an unreasonable and unjustified dislike and/or discrimination against someone that is based on untruths and distortions and ignorance of the true nature of the person...
Hence, describing a lawyer as "bottom-feeding" is not bigotry.
In the same vein, "ambulance-chaser" and "shyster" would not be bigotry.
Simply the truth.
I presume you are a lawyer, as experience has taught me that the bitten dog barks first.
You have my deepest sympathy.
