they denounce big government--they say that government is doing too much and has become too powerful--but supporting at the same time
they denounce big government, they say that government is doing too much and it has become too powerful, while they support at the same time
while they denounce big government, saying that government is doing too much and has become too powerful, at the same time supporting
while they are denouncing big government--they say that government is doing too much and it has become too powerful-- supporting at the same time
while连接两个句子时，在主语相同的情况下，可以省去主语，但必须接动词ing的形式，即：while doing sth. 所以此处supporting的主语就是they。
