My question is: what is the name of mathematicians who ignore the proofs by contradiction and say all of the proofs should be constructive, and what is the name of opposite opinion?

Both descriptions can include multiple perspectives. The first view could describe either constructivists or people who don't accept the law of non-contradiction; this latter group is called paraconsistent logicians. The second view could describe either classical logicians or those who are neither classical nor paraconsistent, such as the intuitionists.
